Question

Mass separation of cells in embryo is

• A. Emboly
• B. Involution
• C. Delamination
• D. Epiboly

Answer 1

The correct option is C Delamination

Emboly is the process in which there occurs an invagination of the blastula to form gastrula.

Involution- A tissue sheet rolls inward to form an underlying layer via bulk movement tissue.

Delamination- Splitting or migration of one sheet into two parallel sheets.

Epiboly- During this movement the cells on one side grow rapidly and surround the slow growing cells on other side and eventually from ectoderm.

So, the correct answer is 'Delamination'.
