Leaves are the part of the tree where photosynthesis takes place. Leaves can come in a variety of shapes, sizes, colors, and textures. The leaves can be gathered in clusters or scattered all over the place. The edges of the leaves can be smooth or serrated. A complete leaf consists of the following three parts: Leaves—mostly broad and flat, suitable for receiving sunlight. The petiole - supports the leaf and connects the leaf to the stem. Stipules - protect young leaves. Some plants have no stipules, and some plants have stipules that fall off very early.
