[Deformation and morphogenesis of Acetabularia cell membrane. II. Local mechanisms of regulating viscoelastic deformations]

Abstract

Relationships between growth velocities of some parts of Acetabularia cell, ratio between the thickness of the cell membrane and apex diameter (its constructive rigidity), intracellular pressure and viscose-elastic deformations are used for physical substantiation of Waddington's concepts concerned with the existence and important search of local morphogenetic mechanisms. Their realization in a strongly deformated regions of Acetabularia cell membrane is shown. The relationship between viscosity, synthesis of the material and dimensions of region and intracellular pressure is found.
