| Abstract: | Isolated spinach chloroplasts and Chlorella cells treated with dichlone (2,3-dichloro-1,4-naphthoquinone) exhibited morphological changes which appeared to be consistent with an alteration of protein elements in the cell. The stroma of dichlone-treated chloroplasts appeared less structured and more homogeneous than that of the control. The cell membrane in dichlone-treated Chlorella cells shrank from the cell wall and exhibited much invagination while the outer membrane of Chlorella chloroplasts appeared wavy. The changes in the cytoplasm of treated Chlorella cells closely reflected those noted in the chloroplast stroma. |
