IONIC COMPOSITION OF THE CYTOPLASM OF NITELLA FLEXILIS
The K, Na and Cl concentrations of the chloroplast layer and the flowing cytoplasm of Nitella flexilis have been determined by applying an internal perfusion technique, which enabled us to avoid contamination of ions from the cell sap. K, Na and Cl concentrations of the chloroplast layer are 110, 26...
