Chapter 25

The "race for sunlight" in plants led to the evolution of the tallest living things in existence, trees. But sunlight is not the only thing that stands to make a tree successful or not in reproducing. Think about how plants function and then answer this question: What are the costs of being taller, as opposed to shorter?

It's sometimes said that plants are much more efficient organisms than animals, in that they consume fewer resources and produce fewer waste products. Evaluate this statement in light of what you have learned about the functioning of angiosperms.
