CHAPTER V THE STEM The stem is the direct prolongation of the plumule of the embryo, and usually grows upwards above the ground. It ' ^'^^ differs from the root not only in the direction of its growth but also in several other re- spects ; thus it bears leaves on its sides while the root bears no leaves, its growing apex is not covered by a protective tissue or cap like that of a root, and the region of it just behind the growing apex is not provided with hairs as is that of a root. The growing apex of the stem is the continuation of the plumule, and consists (fig. 17) of a central axis covered over and protected by a crowd of young and folded leaves.
