The correlation of structure and function--that the shapes of organisms and their various parts matters in how they live and survive--can be obvious or subtle. (Leaves are thin enough that light easily penetrates to all of the light-dependent reactions of photosynthesis yet the shapes of the leaves on a single tree may vary in ways that prevent overheating of the most exposed leaves.) This page and its links explore how size makes a difference and how such difference can force changes in shape to compensate for the effects of size. Be thankful that there can be no birds the size of lions. |
