A tree has three main parts, the roots, the branches and the leaves. Under the ground, the roots spread out so that the tree can stand firm. Above the ground, the roots form the trunk, and the trunk supports the branches.
Near the top of the tree, the trunk divides into branches. At the top of the tree, the leaves grow out of the branches. the leaves receive sunlight to help the whole tree grow.
