. Soils and plant life as related to agriculture . Agriculture; Soils; Plants. 108 SOILS AND PLANT LIFE arifn EXERCISE 35 Object. — To become familiar with a flower and its parts. Procedure. — Lay on the desk before you (1) the flower of a dicotyledon, such as the apple, pear or petunia; also (2) the flower of a monocotyledon, as a head of cane, foxtail or millet, which is just in bloom. Beginning at the stem, compare the flower of the dicotyledon before you with the drawing in Figure 34. At its base, you find five stiff, green leaf-like organs. These are the sepals; and all of them taken together are called the calyx. They afford protection to the 'eofl»///> blossom before it opens. Next above these, we find the petals, pure white or bright in color. Whether united, as they are in the petunia, or separate, as in the apple or pear, the petals make up the corolla. These serve to attract insects. Next, just inside the corolla, we find a number of small, usually yellow, oblong or round bodies, held erect on tiny stems. These are the stamens. The tiny, thread-like stem of each one is the filament, the body at its tip, the anther, and inside the anther, is a powdery substance called the pollen. Lastly, and usually in the center of the flower, we find a part, expanded or divided at the top, and joined by a thread-hke stem somewhat larger than the filament with little seed cavities in the base of the flower. The whole of this central portion is called the pistil; the upper divided or expanded part is the stigma; the lower portion,. C4in Fig. 34. dicotyledonous.
