Expert Solution
Step 1
Gastrulation - It is an early proces of embryonic development in which the implanted blastula develops into three germ layers -

- Mesoderm
- Endoderm
Ingression is a morphogenetic movement during gastrulation. Here, cells leave the epithelial sheet and form freely migrating mesenchymal cells.
