• The senescence and preservation of the structure of the chloroplast in the dark was studied in the protonema of Ceratodon purpureus and in two varieties of pea, a tall variety "Dippe Maj" and a dwarf variety "Early low". The latter variety is better able to survive in darkness, probably because of the larger amount of starch in its chloroplasts. The integrity of the chloroplasts was better preserved in the moss than in the peas. During isolation of the chlorophyll-protein complexes, there was no decrease in the specific activity of the total lamellar extract in any of the dark-grown materials. This contrasts with the turnover of chlorophyll-protein complex (CP) II in the dark-grown moss. In the light, CP II had a half life of two weeks in both the moss and the higher plants, whereas no turnover was evident in CP I. The lack of turnover for CP I is connected with its decrease in senescence.
