Dependence of amplitude oscillatory changes in potential and electrical resistance of Nitellopsis obtusa cell membranes on the stage of cell development

Abstract

The amplitudes of oscillation changes of potential and electrical resistance of Nitellopsis obtusa cell membranes differing from each other in their individual evolution stages were determined. The first, third and fifth cells from the tops of the plants were collected for measurements and only those characterised by rhythmical changes in potential and electrical conductivity of membranes (which revealed one or simultaneously 2-3 types of oscillations) were selected. Visible dependence of the amplitude of investigated changes on developmental stages of the cells, correlating with the intensity of metabolic transformations, was established.
