What is gastrulation? How during gastrulation are the first two germ layers formed? Which are these germ layers?
Submitted by: AdministratorGastrulation is the process through which a portion of the blastula wall undergoes invagination inside the blastocele forming a tube called archenteron (primitive intestine). The cells of the inner side of the tube form the endoderm (germ layer) and the cells of the outer side form the ectoderm (another germ layer). It is the beginning of the tissue differentiation in the embryonic development.
