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 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Guilliermond, Alexandre, 1876-; Atkinson, Lenette May Rogers, 1899-.
