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

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.
