what school rules I want to break if I can.
If I can break the school rules, I will choose to
break the rule for reaching to school on time. Then,
I will sleep till I'm satisfied and then I will
take a morning stroll then I'll go to school.
If it's raining, I will not go to school.

information on capillaries... by gareth
ANATOMY
Blood flows from the heart to breast, which branch and narrow into arterioles, and then branch further still into the capillaries. After the tissue has been perfused, capillaries join and widen to become venules and then widen more to become veins, which return blood to the heart.
The "capillary bed" is the network of capillaries supplying an organ. The more metabolically active the cells, the more capillaries it will require to supply nutrients and carry away waste products.
Metarterioles provide direct communication between arterioles and venules and are important in bypassing the bloodflow through the capillaries. True capillaries branch mainly from metarterioles and provide exchange between cells and the circulation. The internal diameter of 8 μm forces the red blood cells to partially fold into bullet-like shapes and to go into single file in order for them to pass through.
Precapillary sphincters are rings of smooth muscles at the origin of true capillaries that regulate blood flow into true capillaries and thus control blood flow through a tissue.
TYPES
Capillaries come in 3 types:
Continuous - Continuous capillaries have a sealed endothelium and only allow small molecules, like water and ions to diffuse. Continuous capillaries can be further divided into two subtypes:
1.Those with numerous transport vesicles and tight junctions that are primarily found in skeletal muscles, lungs, gonads, and skin.
2.Those with few vesicles and tight junctions that are primarily found in the central nervous system.
Fenestrated - Fenestrated capillaries (derived from "fenestra," the Latin word for "window") have pores in the endothelial cells (60-80 nm in diameter) that are spanned by a diaphragm of radially oriented fibrils and allow small molecules and limited amounts of protein to diffuse. In the renal glomerulus there are larger fenestrae which have no diaphragms. Both types of fenestrated blood vessels have continuous basal lamina and are primarily located in the endocrine glands, intestines, pancreas, and glomeruli of kidney.
Sinusoidal - Sinusoidal or discontinuous capillaries are special fenestrated capillaries that have larger openings (30-40 μm in diameter) in the endothelium to allow red blood cells and serum proteins to enter, a process that is aided by a discontinuous basal lamina. These capillaries lack pinocytotic vesicles and gaps may be present in cell junctions permitting leakage between endothelial cells. Sinusoid blood vessels are primarily located in the liver, spleen, bone marrow, lymph nodes, and adrenal cortex.
It also transports blood to cells, and it is very thin.
PHYSIOLOGY
The capillary wall is a one-layer endothelium so thin that gas and molecules such as oxygen, water, proteins and lipids can pass through them driven by osmotic and hydrostaticification intercontinentalingradients. Catering products such as carbon dioxide and urea can diffuse back into the blood to be carried away for removal from the body. The physics of this exhange is explained by the Starling equation.
The capillary bed usually carries no more than 50% of the amount of blood it could contain, although this amount can be increased through auto regulation by inducing relaxation of smooth muscle in the arterioles that lead to the capillaries bed as well as constriction of the metarteriole. d capillaries (derived from "fenestra," the Latin word for "window") have pores in the endothelial cells (60-80 nm in diameter) that are spanned by a diaphragm of radially oriented fibrils and allow small molecules and limited amounts of protein to diffuse. In the renal glomerulus there are larger fenestrae which have no diaphragms. Both types of fenestrated blood vessels have continuous basal lamina and are primarily located in the endocrine glands, intestines, pancreas, and glomeruli of kidney. Sinusoidal - Sinusoidal or discontinuous capillaries are speci The capillary do not possess this smooth muscles in their own walls, and so any changes in their diameter is massive. Any signaling molecules they release (such as endothalen for constriction and nitric oxide for dilation) act on the smooth muscle cells in the walls of nearby, larger vessels, e.g. arterioles.
Capillary permeability can be increased by the release of certain cytokines, such as in an immune system.
Starling equation is a mathematical model for fluid movement across capillaries:
where:
Jn = net fluid movement between compartments (ml/min)
Kq = Filtration coefficient (ml·min-1·mmHg-1).
Ph = Capillary hydrostatic pressure
Pu = Interstitial hydrostatic pressure
πk = Capillary oncotic pressure
πp = Interstitial oncotic pressure
σ = Reflection coefficient
HISTORY
Ibn al-Nafis theorized a "premonition of the capillary circulation in his assertion that the pulmonary vein receives what comes out of the pulmonary artery, this being the reason for the existence of perceptible passages between the two."
Marcello Malpighi was the first to observe and correctly describe capillaries when he discovered them in a frog's lung in 1661.

which school rule will i break?? by GARETH
HAHA... mine's a funny one... okay.. here it goes.. if i could break a school rule, i would break the " do not break all the school rules" rule!! which means i will be breaking all the rules in a single, free 'break a rule for free thing'.. haha!! yay me!! :P why would i break the school rules? SO STRICT-TIFYING... NOBODY UNDERSTANDS WHY THESE LAME RULES ARE EVEN PUT UP... (sorry.. forgot to turn off my caps lock button) anyway, rules ARE meant to be broken... HEEHEE...
Which school rules would i want to break?
I would want to play truant so that i do not have to come to school so early and not doing homework given by teachers.Even if i am forced to come to school,i would want to wear home clothes to school.....
Which school rule will I break?
I will come to school very late so I do not have to do my prefect duty and not do homework at all.
If I get to break a school rule, what will it be?
If I get to break a school rule, it will be bringing alcohol and cards to school and play during school time...(if i get to break 2 i will choose not having any homework too)=P hahas... By : Cheryl ^.^
Which school rules would i want to break?
I want to break the school rule of the homework! It is very.... Bored... Kind of....=)
If I get to break a SCHOOL LAW what will it be?

P5 NE show experience. ERVIN CHIA
erm.... frankly i liked and hated the NE show... the EYE is quite small and the rain is quite random.. But still, i had fun there too. I liked the fireworks. The gunshots and the bombs were fantastic. I couldn't finish my dinner in time!I liked the view and some jokes there. I've gotta love the show more then hate it!

how do dolpins sleep in water?
Marine mammals such as whales and dolphins spend their entire lives at sea. So how can they sleep and not drown? Observations of bottlenose dolphins in aquariums and zoos, and of whales and dolphins in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal. Individual dolphins also enter a deeper form of sleep, mostly at night. It is called logging because in this state, a dolphin resembles a log floating at the water's surface. Image: John Day Cetacean Behavior Laboratory
UNDER TOW. A baby humpback whale eats and sleeps while being pulled along in its mother's slipstream.
When marine mammals sleep and swim at once, they are in a state similar to napping. Young whales and dolphins actually rest, eat and sleep while their mother swims, towing them along in her slipstream--a placement called echelon swimming. At these times, the mother will also sleep on the move. In fact, she cannot stop swimming for the first several weeks of a newborn's life. If she does for any length of time, the calf will begin to sink; it is not born with enough body fat or blubber to float easily.

Jolice's experience in the NE show
I was totally excited!!! I had never ever go to th national parade before! It is my first time the day before yesterday. I felt that my wish came true. The fireworks are beautiful, and we even see a rainbow....... I could see both the Singapore Flyer and the Esplanade. There is a big ''Eye'' in the middle of the stage. I like to look at the fireworks best. It kind of remind me of my childhood. I took one picture or the fireworks. When the shw is about to end, a sudden downpour came. I am half-soaked when I soak out my raincoat. As I was sooooooo flustered, I tore one BIG hole at the side of the raincoat. I don't really care, and quickly hug my bag under the raincoat. I can't risk getting it wet. It was a pity, as the last fireworks are the most prettiset of all. Xiu Min was not able to see it. It was lucky she was holding her handphne on her hand, for her bag was completely soaked through. She kept on complaining that I feel quite sorry for myself. As we walked down the stairs to go for shelter, water splashed though my legs. I feel like I am walking on a waterfall. We reached schol only at 11.02p.m and I reached home at 11.15p.m. I am extremly tired. But now that I think of it, I think it was quite fun actually.
NE show experience
Last Saturday, 11 July 2009, all Primary 5 students went for the NE show. We wore red T-shirt and school shorts. We met at the school hall for briefing and proceeded to Marina Bay floating platform.
There were parachute performance, dance from different organizations,parade, aeroplane show. The NE show was interesting. Although it rained heavily, we stood up to recite the pledge and sang the National Anthem. We saw fireworks and we felt happy. All of us were wet and shivering in the bus on the way back to school.

How dolphin and whales sleep
Ever wonder how dolphins or whales sleep? They’re mammals just like we are and need oxygen. Well, since when we humans are asleep, we are completely unconscious and do not have to brain capacity to support active thoughts and movement. Then the question is, if dolphins and whales
are just like we are, wouldn’t they drown if they were to fall asleep in the ocean?The answer to that question is obviously no considering dolphins and whales are very much still alive.There is involuntary and voluntary breathing. We humans are involuntary, which means that if we do not breathe, our bodies will automatically try to induce air. Since dolphins and whales have a unique respiratory system which allows them to hold in air for a long period of time, they are voluntary breathers. Voluntary breathers are also known as conscious breathers, which simply means that they need to be conscious in order to breathe because they control when to and when not to breathe.

Ne Show
The NE show was HILARIOUS!! First we went to school. I met Ivanna. Afterwards we all gathered at the hall to receive our "good"ie bag(which was totally not good!). We took our temperature and left to go Marina Bay. When we were there, I thought we were gonna DIE OF HEAT! It was so hot that you could cook fried eggs! Then there was this BIGBIG eye who told us that air con will be on at 7pm! Then we realised "air con" meant the night breeeeze. Soon after a few performances, it started to drizzle. After 2 minutes it stopped. And it carried on for 2 times! The 3rd time it came Ivanna and I thought it was part of NDP performance(after we realised it was real rain) we quickly made a grab for our ponchos and my umbrella. When we reached the shelter, my nose bled suddenly. Ivanna said it was a good thing as i wouldn't worry bout the rain as she said my body's reactions was fast(as after rain it had immediate reactions. SO NOT TRUE!!) Then me and Ivanna shivered on the bus(as we grabbed Jolice's hand for warmness) and listened to songs.

the ne show was so funeee hahas....
i hated the rain
at least my handphone did not kenna tio
after i took my umbrella out ,i became a instant celebrity
hmmm....
i suggest they should serve bags with better straps not straps breaking all over the places.
and provide longer ponchos ......

The fun and horrible NE show!!!
The NE show was fun but it was too bad that it has drizzle two times and there was still one more......That was the "air-con"that pour down from the sky.I did not even get ready and there the"air-con"was there!But,the fun thing was that we had our Fun-pack which is everyone waiting for!The fireworks was very beautiful too!

national day
umm the experience at marina bay it is quite fun but it rain so heavily that there is like havinga waterfall!!!! and when we were coming down the staircase we lose ms zahrinah but we manage to find her....it is quite fun i can say!!!!!it is a memorial thingy because i can remember myself being soak in rain water n shivering in the bus!!!!hahas n one of my friend was sick because of the rain n she was shivering....BOO HOO

Ne show by Celine
Excited for the Ne Show (National educational show),I went to do my homework in the morning to kill time.That day was Saturday,I was afraid that it was going to rain.Soon time came and I got my bag,ready to set off.
When I reached my school,I put down my bag and waited at the hall.Soon,many people came in and sat down.Then we went up the school-bus .After about an hour,we reached there.It was beautiful scenery,there were a lot of trees there.It was a big place.
The weather was cloudy.It then started. I took a lot of pictures and videos.Soon when it was going to finsh,It rained heavily.We went home wet but happy.

My N.E show experience!!! From Xin yi
The N.E. show experience is fun! We played in the rain and we all got wet in the end even though we had our rain coats on... I and Cheryl was so cold in the bus and we tried different ways to keep ourselves warm.Talking back to N.E. show, it had drizzle 2 times! I do not know if my experience of the N.E. show was good or bad. Somehow Good....
last saturday we went to watch the NE show and it was totally amazing sight because we saw MARK LEE!and michelle!wow this is the first time going there! Before we were going for the NE show,we had to take our temperature first,and guess what my temperature was 37.5 degrees!I thought''oh my god!how lucky am i!My temperature was just short of one degrees celsius before i have to be sent down to the general office!''i was like so totally shock but i wasn't sick or feeling unwell i was just normal as usual nothing's wrong with me!Ok i will stop talking with that now,ok after we had arrived at the marina bay,we had to find places to sit.after we had settled down,we started to eat our tibits i was so hungry.and the worse of all after i had ate the bag of ''roller coaster'',i didn't eat any thing for dinner.and suddenly when i was taking a video for the performance,it started raining heaving and i was drenched from head to toe and my bag was wet,not just that,my shoes even got soggy.yuck finishing that,we took the bus but we waited almost a century then the bus finally arrived and we board the bus and went home.the bus was totally cold i was about to close the air con when i realized that actually the closer spoilt and so i had to bare with this but i was really like freezing!
NE Show!
The NE Show was quite nice even though there was the BIG rain....I thought it was a good experience to stand in the rain and get all drenched as that is not something you can do everyday. . . I think l like the fireworks though it disappeared quite fast because of the rain..

The NE show
The NE show ended with a very heavy rain. Despite the heavy rain, I still had a lot of fun watching the show. Maybe the heavy rain was our "air-con" like the "Big Eye" said to switch it at 7pm. The part I liked most is the part before the heavy rain started.
The NE Show!!!
Hi guyz,how r u feeling??? Never mind. Anyway, i'm gonna talk about the NE show.... in the school hall where we were supposed to gather in, recieved our funpacks and our dinner.Together, we waited for about 1 hour bfore we could board the bus to go to marina bay..... When we were at Marina Bay, we walked for quite a LLLLLLLOOOOONNNNNNGGGGGG way bfore i could sit comfortably on my seat. When i finally settled down in my comfortable light green chair, i:

my ne show experience
I had a great time at the NE show.when we were in school,we collected our fun pack and our dinner.after that we board the bus and off we go.the bus ride was about 1 hour or so.when we reach there and went to our seats,we took out our snacks and start eating.at 5.30pm all my friends start eating their dinner.i was surprised on why are they eating so early.At 6.00pm,the show started.suddenly it started raining but after 1 or 2 minutes,it stoped.after 1 to 2 hours the same thing happened it rained again but stoped after a few minutes.At 9.00pm,during the grand finale,it started drizzling.this time I didn't wear my poncho because I know that it will be gone in a few minutes.but after 1 to 2 minutes I saw many of people wearing poncho so I also wear the poncho.when the grand finale was about to end,A heavy rain started pouring down on us!first things first. I shoved my mobile phone and grab my bags. We stand there for about 15 minutes then we left. In the bus I was shivering from head to toe. when i reach home, i had a shower and went to bed and slept almost instantly.

The NE Show
I had a great time at the NE show on Saturday, 11 July 2009. We had nearly an hour drive to Marina Bay. The show started at 6pm, Where a "Big Eye" introduced itself. That "Big Eye" said that it'll switch on the "air-con" at 7pm. Of course, at, 7pm, nothing happened. Sudddenly, at around 9pm where the grand finale was played, there was a heavy rain. After the show, we were all wet but at least we got our "air-con".
My NE Day Experience
To me, the NE day was the most memorable one for I got drenched head to toe. Although we were given raincoats, we still got wet. Luckily, I brought an umbrella with me. I feel that it is very weird that it suddenly rained very heavily. When I went to school that afternoon, the weather was sunny and bright. I waited for about 2 hours before being able to get into the bus which will drive us to Marina Bay.
When we reached there, we proceeded to our seats and sat down to wait for the show to start. Two of the Mediacorp artistes were there hosting the show. The show was very exciting and nice. Before the show, there were some light drizzles and a rainbow appeared but when it was about 8.30pm, it started to rain very heavily.
When I was about to go down the stairs, water was flowing down continously which made the staircase look like a waterfall. When I got home, it was already 11pm. It was a fun but tiring day for me.

The NDP show was fun,funny and was a disater!The video clip was so funny about the army when there was a bomb in Singapore.Mark lee , michelle , and 2 more people were there too!At the Marina Bay it had been raining for a lot of times!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!As the show was about to end suddenly a heavy downpir came it was raining so heavily,nut the rain was cooling.When we were on the bus it was so COLD it seem that it was FREEZING!It was so fun at marina bay!
About NE show
The NE show was very fun but it turned out to be a disaster.I enjoyed myself by eating alot and drinking.The show was nice but the advertisments were dumb.There was 1 problem,why did it have to rain when the show ended during the Grand finale.Does Singapore evaporates that much water in a day?I doubt so.
How do dolphins sleep?
Dolphins have to be conscious to breath.This means that they cannot go into a full deep sleep. Dolphins have "solved" that by letting one half of their brain sleep at a time. This has been determined by doing EEG studies on dolphins. Dolphins sleep about 8 hours day in this fashion. By : Cheryl
NE Show
I feel very excited the time when we I heard about going to the NE Show.THe NE Show was a bit similar to last year's NDP.I like the all the Fire works.They re very beautiful.The "eye" said the Air Conditioner would be on at 8.22 PM but,the Air Conditioner turns out to be the rain.That was an unforgettable experience in my life.

NE show
I felt so excited going to the ndp show. it took us about an hour to reach the floating stadium at marina bay. When we arrived , it was packed with people. During about 7 .50, it started to rain heavily. My shirt, pants and shoe was soaking wet . Altough I was wet, I had a good time at there.

I was so excited!We sat on the bus for more than 30 mins and reach there finally. The show was wonderful but in the end of the show, it started to rain heavily. I was drenched from head to toes. Luckily i have umbrella with me but it was no use at all. My shoes was soaked with water and i have no shoes to wear on Monday. Overall , I think it was exciting.

My NE show experience ? Actually,it would be perfect if isn't for the rain. was drenched and was freezing cold in the bus. Luckily, I have my best friend XinYi =)... But generally the show was excellent. I can even say it was perfect ( except for the marching , it was quite boring )I love the Sangnila Utama part the most By: Cheryl =)
Does dolphins sleep??
Dolphins, like humans, are mammals. They are warm-blooded, bear live young, breathe air, and they require sleep. However, for dolphins, sleeping and breathing at the same time can pose a bit of a problem. Humans are able to breathe during sleep as they live on land and can perform the task unconsciously. However, dolphins are aquatic mammals; they must actively make the decision to breathe and come up to the surface for air. Fortunately, as Bob Holmes notes in his May 1, 2009 article "'Brain-juggling' lets dolphins avoid sleep deprivation" published in NewScientist, nature has come up with a remarkable solution to the problem so that dolphins sleep without drowning.
How Do Dolphins Sleep?
The February 2, 1998 Scientific American article "How do whales and dolphins sleep without drowning" describes this interesting process of dolphin sleeping. Dolphins are able to send one half of their brain to sleep at a time so that they are never completely unconscious.The other half of the brain monitors what’s going on, ensuring that the animal stays out of danger and continues to breathe. Which half sleeps switches from nap to nap. Dolphins often swim with dolphins in groups called pods. During sleep they keep at least one eye open, allowing them to stay in contact with the others in the pod and coordinate their movements. Although they could likely sleep anywhere, usually dolphins sleep near the surface so that they can come up for air easily. These creatures can often be seen swimming slowly near the surface with little movement. This action is called “logging” and these dolphins are at rest.
Do Dolphins Have Dreams?
Perhaps dolphins dream about their day, eating, chatting with other dolphins, a round-the-world swim with dolphins in pods. The truth is nobody knows for sure. However, Margaret Klinowska does note in her September 26, 1994 essay “Brains, Behaviour and Intelligence in Cetaceans” published in the second edition of 11 Essays on Whales and Man, that dolphins are one of the few mammals that do not have REM sleep. Humans sleep during the REM stage of the sleep cycle. One could deduce that if dolphins don’t have a REM stage, then they can’t have dreams. However, some scientists dispute this claim and say dolphins merely have very low levels of REM sleep. It’s also possible that dolphins sleep and dream differently from humans. Studies done on captive belugas and grey whales show that these aquatic mammals sometimes have muscular spasms during their brief REM stage, which could be associated with dreaming.
How Do Scientists Know Dolphins Sleep?
Scientists don’t just swim with dolphins and watch them for hours, although observation is an important component of their studies. The 1998 Scientific American article describes how scientists use electroencephalography – hooking up electrodes to captive dolphins’ heads and measuring the electricity levels in their brains. The resulting data is an electroencephalogram or EEG. The EEG shows that during sleep, half of the dolphin’s brain is active while the other half shuts down. Studies show that dolphins sleep about eight hours a day.

The NE Show!!!
The NE show was interesting and fun. Especially with your classmates, it is more interesting!!! Even though at the start, there is lots of free time as they are doing some preparation, but it is not boring as we have friends to chat with!:) Unfortunately, the weather forcast said that it is going to rain! I am very worried if the show would be cancel because it is once in a lifetime. The first time, it stated drizzling but then it reurn to normal. At the second time, it started drizzling again but stopped. BUT at the third time, after reapeting the same cycle, it came out a rainbow! I was amused and thought that it would not rain again.So we continue watching the show. At night, it was the grand finale, and all the participants came out for their last act. All of a sudden, I heard a loud thunder"BOOM"!!! Here comes a heavy down pour, all students took out their ponchos and immediately wear them. It was a very heavy rain and all of us were shivering! I pity the performers as it was the grand finale and all of them came out and got wet because of the rain but they still continued with the show. I did not bring a umbrella so I was soaked profusely. My hands were cold and the worst is I did not get to watch the last part of the show as I am focusing on how to avoid the rain! I went on the bus and i was turned into ice. The aircon was not on but it seems like we are walking into a freezer! When I reached the school, I walked home and asked my mom to cook me a bowl of hot instant noodles. It was nice. When I bath, I felt that my hands are numb! So overall, I enjoyed myself despite the heavy downpour.
NE show
I liked the NE show as it is very interesting. However, some parts were boring and some parts were funny. I did not like the waiting especially the advertisements and the songs. The part that I liked was the part about the news and the story. I actually thought the last part (Grand Finale) would be good but it was not enjoyable because of the rain. I hope I will have another chance to go there again.

NDP SHOW
WELL,EVERY YEAR IS ALMOST DE SAME......QUITE OKAY,BUT STLL ROOM FOR IMPROVEMENT. LIKE DE SANILA UTAMA(DID I SPELL CORRECTLY?)IT LOOKS QUITE SILY.GENERALLY,QUITE OKAY,BUT THE RAIN RUINED DE SHOW AT THE LAST PART.I WAS FREEZIN' ON DE BUZ.ACTUALLY I WANTED TO TELL DE BUZ DRIVER TO TURN AIRCON OFF,BUT.......OH WELL.....!
The NDP show rehearsal!!!
I was excited when i heard that we were going to the NDP show rehearsal!But,we had to wait in school for like 1 hour!!!After that,we boarded the bus and headed there.It was like the trip lasted for more than an hour!!!When we reached there,the whole stage was so huge!We enjoyed all the shows and the fireworks were so beautiful!But at the last firework,it started to rain!We were drenched from head to toe!My phone was like spoilt,but it somehow ''recovered'' after i restarted the whole thing.Reinvs,especially those who had umbrellas,were so popular as many people wanted to share umbrellas[i was one of them who approached reinvs........]It was very fun and if there is another chance to go,i would still want to go.
NE show on 11th July 09 (done by Zilin)
On 11th July 2009, all the primary five students went to the Marina barrage to watch the national day rehersal.I was excited.Things were going find in the begining ,but it soon stated to rain heavily.All of us was drenched from head to toe. Some of handphones were also wet and spoiled. Luckily I brought an umbrella with me.But it was no use , I was also drenched from head to toe even with my umbrella withb me.Although it rained, I still enjoied myself.

Why do plants need nitrogen?
All plants need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Nitrogen is a limiting factor for plant growth.

plants need nitrogen?
Plants need nitrogen? Yes, they do. All plants and animals need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. The molecules of nitrogen in the atmosphere can become usable for living things when they are broken apart during lightning strikes or fires, by certain types of bacteria, or by bacteria associated with legume plants. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Nitrogen is a limiting factor for plant growth. By:Cheryl

why do plants need nitrogen?
Plants use nitrogen by absorbing either nitrate or ammonium through the roots. Most of the nitrogen is used by the plant to produce protein (in the form of enzymes) and nucleic acids. Nitrogen is readily transported through the plant from older tissue to younger tissue. Therefore, a plant deficient in nitrogen will show yellowing in the older leaves due to the underdevelopment or destruction of chloroplasts.(1)The reason why plants cant use nitrogen from the air is because it is in its gas form N2. Plants cant use nitrogen in this form so it therefore needs to be turned into either nitrate or ammonium before it can be utilised by the plant. This can be done through nitrogen fixation which can be accomplished by bacteria for example.

Nitrogen is an element that is found in both the living portion of our planet and the inorganic parts of the Earth system. The nitrogen cycle is one of the biogeochemical cycles and is very important for ecosystems. Nitrogen moves slowly through the cycle and is stored in reservoirs such as the atmosphere, living organisms, soils, and oceans along its way.
Most of the nitrogen on Earth is in the atmosphere. Approximately 80% of the molecules in Earth's atmosphere are made of two nitrogen atoms bonded together (N2). All plants and animals need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. The molecules of nitrogen in the atmosphere can become usable for living things when they are broken apart during lightning strikes or fires, by certain types of bacteria, or by bacteria associated with legume plants. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Nitrogen is a limiting factor for plant growth. Animals get the nitrogen they need by consuming plants or other animals that contain organic molecules composed partially of nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into the oceans. As dead plants and animals decompose, nitrogen is converted into inorganic forms such as ammonium salts (NH4+ ) by a process called mineralization. The ammonium salts are absorbed onto clay in the soil and then chemically altered by bacteria into nitrite (NO2-) and then nitrate (NO3- ). Nitrate is the form commonly used by plants. It is easily dissolved in water and leached from the soil system. Dissolved nitrate can be returned to the atmosphere by certain bacteria in a process called denitrification.
Certain actions of humans are causing changes to the nitrogen cycle and the amount of nitrogen that is stored in reservoirs. The use of nitrogen-rich fertilizers can cause nutrient loading in nearby waterways as nitrates from the fertilizer wash into streams and ponds. The increased nitrate levels cause plants to grow rapidly until they use up the nitrate supply and die. The number of herbivores will increase when the plant supply increases and then the herbivores are left without a food source when the plants die. In this way, changes in nutrient supply will affect the entire food chain. Additionally, humans are altering the nitrogen cycle by burning fossil fuels and forests, which releases various solid forms of nitrogen. Farming also affects the nitrogen cycle. The waste associated with livestock farming releases a large amount of nitrogen into soil and water. In the same way, sewage waste adds nitrogen to soils and water

Why do plants need nitrogen and magnesium?
Nitrogen is an important component of many important structural, genetic and metabolic compounds in plant cells. it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide. it is also major component of amino acids, the building blocks of proteins. Nitrogen is a component of energy-transfer compounds, such as ATP which allows cells to conserve and use the energy released in metabolism. nitrogen is a significant component of nucleic acids such as, DNA, the genetic material that allows reproduction. Phosphorus is an essential nutrient both as a part of several key plant structure compounds and as a catalysis in the conversion of numerous key biochemical reactions in plants. Phosphorus is noted especially for its role in capturing and converting the sun’s energy into useful plant compounds. The two examples that follow illustrate how vital phosphorus nutrition is to normal plant development and production. Phosphorus is a vital component of DNA, the genetic "memory unit" of all living things. Itis also a component of RNA, the compound that reads the DNA genetic code to build proteins and other compounds essential for plant structure, seed yield, and genetic transfer. The structures of both DNA and RNA are linked together by phosphorus-bonds.Phosphorus is a vital component of ATP, the "energy unit" of plants. ATP forms during photosynthesis, has phosphorus in its structure, and processes from the beginning of seedling growth through to the formation of grain and maturity. Thus, phosphorus is essential for the general health and vigor of all plants.Some specific growth factors that have been associated with phosphorus are: stimulated root development, increased stalk and stem strength, improved flower formation and seed production, more uniform and earlier crop maturity, increased nitrogen N-fixing capacity of legumes, improvements in crop quality, and increased resistance to plant diseases.
Dictionary:
Phosphorus: A highly reactive, poisonous, non-metallic element occurring naturally in phosphates, especially apatite, and existing in three allotropic forms, white (or sometimes yellow), red, and black. An essential constituent of protoplasm, it is used in safety matches, pyrotechnics, incendiary shells, and fertilizers and to protect metal surfaces from corrosion. Atomic number 15; atomic weight 30.9738; melting point (white) 44.1°C; boiling point 280°C; specific gravity (white) 1.82; valence 3, 5.
RNA: Short for ribonucleic acid. The nucleic acid that is used in key metabolic processes for all steps of protein synthesis in all living cells and carries the genetic information of many viruses. Unlike double-stranded DNA, RNA consists of a single strand of nucleotides, and it occurs in a variety of lengths and shapes. RNA also differs from DNA in having the pyrimidine base uracil instead of thymine and in having ribose instead of deoxyribose in its sugar-phosphate backbone. In eukaryotes, RNA is produced in the cell nucleus. Messenger RNA is RNA that carries genetic information from the cell nucleus to the structures in the cytoplasm (known as ribosomes) where protein synthesis takes place. Ribosomal RNA is the main structural component of the ribosome. Transfer RNA is RNA that delivers the amino acids necessary for protein synthesis to the ribosomes.
