The cytoplasm of the plant cell cytoplasmofplant00guil Year: 1941 Chapter XI 119 — Role of Ghondriosomes SKY, DuESBERG, LEVI, and MiLOViDOV, is today abandoned by PoR- TIER himself. Nevertheless it had the merit of initiating investi- gations which have produced methods by which chondriosomes can be distinguished in cells from symbiotic and parasitic bacteria, CowDRY and Olitsky, Duesberg, and Milovidov have described methods by which, in the cells of nodules of legumes and in the adipose cells of cockroaches, symbiotic bacteria can be distin- guished from the chondriosomes by means of differential staining. By these methods MiLOVlDOV found that the symbiotic bacteria and the chondriosomes, including the plastids, are both distributed to the daughter cells during mitosis but not in the same manner. He has demonstrated, besides, that centrifuging brings about a dis- placement of the symbiotic bacteria in the direction of the centri- fugal force but has no influence on the chondriosomes and plastids. The symbiotic bacteria, therefore, are heavier than the cytoplasm and are heavier than the chondriosomes and plastids. (Figs. 80, 81). This work on animal cells led Regaud to consider the chondrio- somes as 'organelles having an eclec- tic and pharmaceutical function in the cell' , as 'electosomes'. Ac- cording to this theory, the chondrio- somes by means of a physico-chemical mechanism still unknown, draw from the surrounding medium the mate- rials necessary to the life of the cell, transform them and finally release the product of elaboration, so that it may be excreted or kept in reserve. An analogous theory was applied by P. A. Dangeard to his 'vacuome' which he likened to the chondriome. Mayer and Schaeffer, basing their idea on reports according to which the fatty acids contained in the lecithins are made to play the role of self-oxidizing bodies have suggested that the chondrio- somes, by virtue
