Contents of the central vacuole (cell sap) were separated from internodal cells of Nitella and Chara. Most of the acid phosphatase and carboxypeptidase, which are marker enzymes for lysosomes, were detected in the separated cell sap. In contrast, most of the catalase, cytochrome oxidase, NADPH_2-cytochrome c reductase, and glucose-6-phosphate dehydrogenase were detected in parts of the cell other than the cell sap: which shows there is relatively little contamination of the cytoplasm in the separated cell sap. Enzymatic properties of the carboxypeptidase in Nitella axil-liformis were similar to those of carboxypeptidases in higher plants and those of cathepsin A in animal lysosomes. These results indicate that the central vacuole of Charophyta has some properties of the lysosome.
