Default Why Do Leaves Have Such Different Shapes?

Why Do Leaves Have Such Different Shapes?


There’s one thing about leaves that science has long agreed upon: They only grow so big as available water allows — but not so big that the whole plant overheats.

The water part makes sense. We all need water to grow. And the sun? Leaves collect those rays and, through photosynthesis, convert them into food.

Too much direct sunlight and that photosynthetic engine spins hot and risks burning out.
