The cytoplasm of the plant cell cytoplasmofplant00guil Year: 1941 Chapter XIV 157 — The Vacuolar System seem to be encountered in all cells in all phases of development and that, in general, they appear in embryonic cells as minute elements composed of a very concentrated colloidal solution and that they sometimes show a great resemblance in form and dimensions to the chondriosomes. These chondriosome-shaped elements swell and are transformed into large liquid vacuoles containing very dilute colloidal solutions. These facts do not, however, confirm Dange- ard's interpretation in which he identifies the vacuolar system with the chondriome. Although in some cells the young vacuoles present forms almost identical with those of the chondriosome, there are other very numerous cases in which the young vacuoles, on the contrary, have an appearance which does not permit of any confusion with the chondriosomes. For example, in some algae, the vacuoles remain constantly in the state of large liquid inclusions. Nev- ertheless, since it is evident that these two categories of elements may sometimes be easily mistaken for one another, it is advisable to examine here the characteristics which make it possible to distinguish between them. hhpf
