Abstract

The stem bears lateral organs, the leaves. These occur at definite points, the nodes, and originate in an exogeneous manner. The leaf arises in the form of a papilla and is not covered by the superficial tissue as the root is. The mature leaf is divided into two parts, the blade and the sheath. At the base of the blade occurs the membranaceous ligule. The veins of the leaf are parallel and are continuous with those of the sheath. The vascular bundles of the sheath connect with those of the stem. The function of the leaf is the preparation of food by a process known as photosynthesis. This same function is also shared by the sheath and stem, but not in nearly so marked a degree.
