title: [Deformation and morphogenesis of Acetabularia cell membrane. I. Relation of deformation to genetic and geometric factors].
abstract: Relationships between the changes of geometric shape, volume and deformations of the apical growth part of acetabularia cell are studied. Jung module E approximately 25 kg/cm2, viscosity coefficient of the apex cell theta 4 - 10(4) kg-sec/cm2 and intracellular pressure P approximately 1 kg/cm2 are measured. Cell shape formation according to Waddington is concerned with simple physical factors which are under the genetic control. It is shown that uneven deformations with the loss of shape stability bring about periodic cell complications.
