Vedclass · Answer

(A) Gastrulation is a phase in early embryonic development during which the single-layered blastula is reorganized into a multilayered structure known as the gastrula. This process involves the movement of cells to form the three primary germ layers: ectoderm,mesoderm,and endoderm. It occurs immediately after the formation of the blastula (which is the result of cleavage). Therefore,the process marks the beginning of the differentiation of germ layers.
