Question

Quizplus · Accepted Answer

Cell migration occurs during both gastrulation and organogenesis. During gastrulation, cells move from the surface of the blastula to the interior, forming the three germ cell layers. During organogenesis, cells migrate to specific locations to form organs and tissues. Cell migration does not occur extensively during cleavage, which is primarily a cell division process.
