Plant propagation. Fig. 1.—TEAST CELLS. mixied by the aid of the most powerful microscopes. Bnt down here, at or near the unit of vegetable life, we find perfect plants that consist of only a single cell, and among the most familiar of them is the yeast plant {Torula cerevisiw) A cluster of these one-celled plants, highly magnified, is shown in figure 1. There are different species of yeast plants, each of a different form, and all may be propagated, under proper conditions, as readily as plants of higher orders. The Bac- teria are among the most minute and obscure race of one-celled organisms, and the in- terest in these is increased on account of their frequent association with many of the diseases of the higher order of plants and of ani- mals. There are hundreds and thousands of species of these minute one-celled plants, and they assume a great va- riety of forms; some are sim- ple round dots floating in liquid, others in chains of cells, while some species are ornamented in the most intri- cate geometric patterns, while others are oval, long, or spread out in a fan-shape, as shown in the one-celled alga (Lic- mophora splendida), figure 2. While these minute one-celled plants play an impor- tant part in the development and continuation of plant- life, still their small size has, in a measure, prevented a very general acquaintance with their structure and properties, as well as making it somewhat difficult to.
