The cytoplasm of the plant cell cytoplasmofplant00guil Year: 1941 Guilliermond - Atkinson — 156 — Cytoplasm In most fungi, except for the Phycomycetes, the vacuoles appear in the tips of the growing hyphae as very numerous, small, globular elements which sometimes stain uniformly and deeply with the vital dyes and sometimes remain uncolored but contain a deeply stained corpuscle showing Brownian movement (Fig. 100). These vacuoles swell in regions farther away from the tip, then coalesce, until, in the regions still farther away, they form large colorless vacuoles filled with deeply stained corpuscles. These bodies swell after a time, then may dissolve and give the vacuole a diffuse and homogeneous color. This is also true in the yeasts in which there exist in the bud several small, spherical vacuoles, sometimes uni- formly stained with neutral red, sometimes not stained at all, but containing colored corpuscles. These small vacuoles fuse during the growth of the bud until there is present only one large vacu- ole or a few large vacuoles filled with stained cor- puscles showing Brownian movement. (Fig. 101). In some of the lower plants, the vacuoles de- velop quite differently. In many algae, the Con- jugatae for example, they are always in the form of large liquid vacuoles. In other algae they may, on the contrary, appear during the entire cellular development as very small, semi-fluid, usually globular, vacuoles, scattered about in the cytoplasm and never undergoing hydra- ,„SXnJ;;-t.'vftai tion.
