What part of a tree helps the leaves get as much sunlight as possible?

The part of a tree that helps the leaves get as much sunlight as possible is the crown, which consists of the tree's branches and leaves. The crown's structure allows leaves to spread out and orient themselves toward the sun, maximizing photosynthesis. Additionally, the height of the tree enables it to compete for sunlight above surrounding vegetation. This arrangement ensures that leaves receive optimal light exposure throughout the day.
