Question

What-is-blastula-and-gastrula?

Answer 1

During gastrulation cells migrate to the interior of the blastula, subsequently forming two (in diploblastic animals) or three (triploblastic) germ layers. The embryo during this process is called agastrula. The germ layers are referred to as the ectoderm, mesoderm and endoderm.
