• The light-induced recovery of cell division and chloroplast development in "giant", "bleached" cells of the Emerson strain of Chlorella is unaffected by treatments (atrazine, CMU, incubation in a CO_2-free atmosphere) which interfere with photosynthesis. Anaerobic conditions or the presence of respiratory inhibitors (DNP, KCN, NaN_3) markedly suppress recovery. Recovery is accompanied by a mobilization of the reserve starch which follows a linear course over the first 9 hr. Chloramphenicol (50 μg/ml), which inhibits chlorophyll synthesis and the development of a photosynthetic capacity, is without effect on the early rate of starch mobilization. Evidence is presented that the contribution of photosynthesis towards recovery is only significant when the reserve starch has been depleted. Recovery does not require continuous light; the critical light-stimulated processes apparently taking place during the first 9 hr. The possible nature of the light stimulation of recovery is discussed.
