The Stem System.—The stem of a plant is the part that bears the buds, leaves, flowers and fruits. Its office is to hold up these parts to the light and air; and through its tissues the various food-materials and nutrients in solu- tion in water are distributed to the parts of the plant. 35. The entire mass or fabric of stems of any plant is called its stem system. (Figs. 4, 17.) The stem system may be her- baceous or woody, annual, bien- nial, or perennial; and i

The Stem System.—The stem of a plant is the part that bears the buds, leaves, flowers and fruits. Its office is to hold up these parts to the light and air; and through its tissues the various food-materials and nutrients in solu- tion in water are distributed to the parts of the plant. 35. The entire mass or fabric of stems of any plant is called its stem system. (Figs. 4, 17.) The stem system may be her- baceous or woody, annual, bien- nial, or perennial; and it may assume many different sizes and shapes. (Paragraphs 11 to 13.) 36. Stems are of many forms. The general way in which a plant grows is called its habit. The habit is the appearance or looks. Its habit may be open or loose, dense, straight, crooked, compact, straggling, climbing, erect, weak,, strong, and the like. The roots and leaves are the important func- tional or working parts : the stem merely connects them, and its form is exceedingly variable. 37. Kinds of Stems.—The stem may be so short as to be scarcely distinguishable. In such cases the crown of the plant—that part just at the surface of the ground—bears the leaves and flowers; but this crown is really a very short stem. The dandelion (Fig. 8) is an example. Such plants (13). 17. Stem system of an apple tree.
