Will plants be affected if it is too hot or too cold?

It can be difficult to tell if a plant has endured too much cold or too much heat, but wilted leaves that yellow and fall off are associated with too much heat and light. Wilted or curled leaves that are discoloured or brown and dropping are signs a plant has faced temperatures that are too cold for it.So I conclude that plants cannot live in places too hot or too cold except for the cactus.
