Question

Leaves need to be elevated so they are exposed to sunlight for photosynthesis. Which part of the stem grows to make this possible?

Answer 1

The answer is apical meristem.

An apical meristem is a meristem tissue found at the tips of branches. When the apical meristem is active, a tree grows in height. By growing in height, leaves will be elevated and that way exposed to the sunlight so the process of photosynthesis can take place.
