1. Meaning of Gastrulation:
The blastula passes into the stage called gastrula by the process—Gastrulation. This process is extremely important in the ontogenetic process of an animal, because the blue-print of the future organisation is laid down during this phase.
During this crucial and dynamic process major presumptive organ-forming areas of the blastula become reorganised in a fashion that allows their ready transformation into the fundamental body plan of a species. Gastrulation is essentially a process of migration of cells from one place to the other in the embryo. Besides movement of cells, considerable nuclear differentiation also takes place.
In almost all animals it results in:
(i) The establishment and differentiation of three primary germinal layers—ectoderm, mesoderm and endoderm,
(ii) The establishment of nuclear differentiation and
ADVERTISEMENTS:
(iii) The beginning of the control of genetic factors over development.
