Effects of mannitol hypertonicity on water and ion contents in the alga Hydrodictyon reticulatum.
Long-term effects of mannitol hypertonicity on the water and ion contents in the fresh-water alga Hydrodictyon reticulatum were studied. The cells did not behave as osmometers and a closer examination suggested that wall elasticity was related to the medium tonicity and that the rate of sodium extrusion from the cells depended on the wall (turgor) pressure.
