The effect of indol-3-acetic acid (lAA) and calcium (Ca + + ) on the flow of water through Nitella celIs was studied. Nitella cernua Braun was selected because it is possible tb study the permeability of a single isolated cell. IAA was used at a concentration of 0,28 10-3 M and CaCI2 at 10-3 M. The effect of IAA on the isolated celIs was confirmed by the increase of plasticity and permeability of the plasmalema of th.e treated cells with absorption and a consequent elimination of water. The effect was reversed by Ca ions.
