Summary The reduction of the rotational chloroplast motion velocity (CMV) during the exposure of Elodea cells to hypertonic solutions of PEG-4000 is satisfactorily described by an exponent. The dynamics of reduction correlates with the dynamic equilibration time (T eq ) between osmotic potentials of cell cytoplasm and external solution. The acceleration of the chloroplast motion, for example by gadolinium ions, results in the reduction of T eq , and this is supposed to be due to the increase of the con tribution of the near-membrane Nernst layers to transmembrane transfer resistance resulting from the «blowing-off» of a part of the layer by moving cytoplasm. |
