. The cytoplasm of the plant cell. Plant cells and tissues; Protoplasm. Chapter II 7 — General Facts which impregnate the cytoplasm and can be detected only by using certain microchemical reagents. All these products arise by cjrto- plasmic activity and a distinction must therefore be made between them and the cytoplasm by which they were pro- duced. These products are grouped under the term pm'aplasm or deutoplasm and are separated from the cytoplasm, which, with the plastids and chondriosomes, constitute living substance. Among the products resulting from the activity of the cytoplasm are some which are of permanent char- acter, such as the cellulose wall. This is a cyto- plasmic secretion which persists during the entire life of the cells and can not, it would seem, be considered as belonging to living substance. These permanent formations of the paraplasm or deutoplasm are specified as metaplasm. Lastly, the name protoplast is used to designate all the contents of the cell except the cell wall, , the protoplasm and paraplasm together. In the cytoplasm, then, we shall have to con- sider the cytoplasm itself, the plastids, the chon- driosomes and the paraplasm, the most important constituents of the last category being the vacu- oles and the lipide granules. These, and other paraplasmic formations not listed above, will be studied in the succeeding Fig. 2. — Semidia- grammatic represen- tation of a living epidermal cell of Al- lium.
