I noticed how light shines through the leaves of this plant. The leaves are spread out so the light gets to most of them. Looking at trees, I can see the leaves do the same thing. They spread out and don’t overlap much. If you look closely at trees and other plants you can see the leaf pattern fitting together like a jigsaw puzzle. Sometimes when you see a bush the leaves are all on the outside, close fitting, and the centre is just branches and twigs. The internal area has been shaded out by the ball of leaves around it. Maximum photosynthesis and maximum food for the plants. Nature is wonderful, and evolution is amazing.
