[Mechanical and chemical patterns in the completion of isolated cell division].

Bicellular complex of a divided oocyte of the mollusc Lymnea stagnalis is chosen as a "testing machine" for studying mechanical and biochemical properties of the membranes of interblastomere wall. The membrane material is described by a standard rheological body. Rheological and kinetic problems are considered. Their solution allows an experimental solution of elastic, viscose and relaxation constants and chemical-mechanical parameter of the balance of the membrane synthesis and its deformations. A relationship (of the logistic type) between the growth of the wall area and time is found.
