Some of the chondrio- somes later, at germination, form the amyloplasts of the root and the chloroplasts of the chlorophyll-bearing organs (leaves, etc.). It has been proved by our research that chondriosomes exist per- manently in all phanerogam cells and that they are transmitted by division from one cell to the next.

Fig. 51. — Portion of the embryo sac of Lilium eandi- dum. 1, 2, stages in the development of the plastids (P) and the mitochondria (M); 3, digestion in the plastids. The origin of plastids, which for so long remained obscure in the phanerogams, is now well known, through the use of mito- chondrial techniques, by means of which a chondriome has been demonstrated in embryonic cells analogous to that in animal cells. The entire life history of this chondriome has been followed and it has been shown that events take place as if the plastids arose by differentiation of some of the elements of the chondriome.
