Vedclass · Answer

(B) The $archenteron$ is the primitive gut cavity that forms during the process of $gastrulation$. During the $gastrula$ stage,the embryo undergoes cell migration and rearrangement to form the three germ layers: $ectoderm$,$mesoderm$,and $endoderm$. The $archenteron$ is formed by the invagination of cells into the $blastocoel$,eventually developing into the digestive tract of the organism. Therefore,the $archenteron$ is characteristic of the $gastrula$ stage.

In which stage is the archenteron cavity observed?
