In trees, leaf nodes are also called external nodes or terminal nodes. Thus, the leaves are long and narrow, with a sheathing surrounding the stem at the base. Functions of Leaf Blade The leaf consist of a broad, flat part called the lamina, which is joined to the rest of the plant by a leaf stalk or petiole. Most green plants have leaves that are broad, flat, and exposed to capture as much of the sun's energy . The outer walls of the cells are covered with the protective layer, the cuticle. This sugar is the primary source of food for trees. The structure of the roots The water absorbed by the root hair cells passes through the plant in xylem tubes and eventually reaches the leaves.
