Vedclass · Answer

(D) Gastrulation is a phase in embryonic development during which the single-layered blastula is reorganized into a multilayered structure known as the gastrula. Key features of gastrulation include: $1$. The formation of the archenteron (primitive gut). $2$. The differentiation of the three primary germinal layers: ectoderm,mesoderm,and endoderm. $3$. Extensive morphogenetic movements of cells. Option $(d)$ is incorrect because blastomeres do not degenerate; they rearrange and differentiate to form the germ layers,and the blastocoel is gradually obliterated by the expanding archenteron,not through degeneration.
