Question

why are the leaves of tall trtees smaller than the leaves of shorter trees?

Answer 1

Answer:

TYPICALLY, the taller the tree, the smaller its leaves. ... Sugars produced in leaves diffuse through a network of tube-shaped cells called the phloem. Sugars accelerate as they move, so the bigger the leaves the faster they reach the rest of the plant. But the phloem in stems, branches and the trunk acts as a bottleneck.
