Water permeability of the plasma membrane of a Characean internodal cell decreased with an increase in the osmotic pressure of the outside of the cell, suggesting that the equivalent pore radius of the water-filled pores becomes smaller with an increase in the osmotic pressure. In contrast, the apparent membrane resistance did not increase with an increase in the external osmotic pressure. These facts suggest that ions pass through the membrane mainly via pores other than those for bulk water flow.
