Abstract

B R I E F N 0 T E done in dim green light (Kodak Wratten safelight filter, series 7) . Under these conditions, cell division ceases after 2-3 days . Chloroplast development in the absence of cell division was induced by placing such a dark-starved culture in the light 3 days after adding the cells to the substrate-free medium . Four cultures were used in the radioautographic experiments : (a) a culture of dark-grown dividing cells which contained 5 .1 X 10 6 cells per ml and 0.4 X 10-10 mg chlorophyll a per cell, (b) a culture of dark-grown dividing cells (a duplicate of culture a) which had been illuminated for 19 hr prior to the experiment and contained 4.9 X 10 6 cells per ml and 5 .4 X 10 -10 mg chlorophyll a per cell, (c) a culture of dark-starved, nondividing cells which contained 3 .8 X 106 cells per ml and 1 .1 X 10-10 mg chlorophyll a per cell, and (d) a culture of dark-starved nondividing cells (a duplicate of culture c) which had been preilluminated for 12 hr and contained 3 .7 X 106 cells per ml and 5 .0 X
