[Increase in the rigidity of bioconstruction material during the process of morphogenesis].
Structural rigidity of the material of cell wall in the cylindrical part of Acetabularia apex resulting from the fibrillar structure and of the cell wall properties and deformations realized during anisotropy, were studied. Values of Jung's moduli and Poisson's coefficient of the growing wall were obtained. It was shown that anisotropy of the material featured inner geometrical rigidity of the bioconstruction which restricted the deformations, and in case of structural instability predetermined their morphogenetic switching.
