Vedclass · Answer

(D) Gastrulation is a phase in early embryonic development during which the single-layered blastula is reorganized into a multilayered structure known as the gastrula. Key events during gastrulation include: $1$. Morphogenetic movements of cells to their appropriate positions. $2$. Formation of the three primary germ layers: ectoderm,mesoderm,and endoderm. $3$. Formation of the archenteron (primitive gut). $4$. The blastocoel is gradually obliterated (reduced) as the archenteron forms,but it does not involve the 'degeneration of blastomeres' as a defining characteristic. Therefore,option $D$ is the incorrect statement.

Which of the following is $NOT$ true for gastrulation?
