title: [On the theory of action potential propagation in plant cells].
abstract: The distribution of an electric field in plant cells and zooblasts has been investigated at propagation of the action potential. The behavior of ions in the cytoplasm and in the extracellular fluid has been described with the equations of electric charge motion in the electrolytes. It has been shown that the action potential causes an electric potential change not only in the depth of the cytoplasm but also in the extracellular area far from the lipidic bilayer. The biomembrane resistance has been expressed by physical parameters of a cell, such as ionic diffusion coefficient in fluid, Debye-Huckel radius, dielectric conductivity etc. The presence of breakings in the action potential diagrams has been explained as a result of insufficient resolving power of the measuring devices at the instant the sodium ionic canals of the bilayer opens.
