INDIVIDUAL VEGETABLE CELLS. 31 star-shaped, hour-glass shaped, disk-shaped, tubular, many-sided, or of any other form. (Fig. 8. ) 9. The bioplasm within the cell-wall may be trans- formed into a great variety of formed material, mak- ing special cell-contents. These may be solid, as col- oring matter, starch, crystals, and resin ; or flui...d, as oil and gum, or solutions of sugar or tannin. The most important of these substances is called Chlvro ptytt) (Gr. Chloros, green; phyllon, a leaf, ) or the source of the green color of plants. It is com- posed of a peculiar coloring matter intimately united with separate particles of bioplasm, which, under the influence of sunlight, causes the absorption of car- bonic acid gas from the air, which is necessary to nourish the plant. Starch is also an important prod- uct of vegetable cells, even more widely distributed than chlorophyll.
