In which stage of development, germ layers are formed?
Correct answer: C. Gastrulation
- A. Morulation
- B. Blastulation
- C. Gastrulation
- D. Organogenesis
Explanation
Germ layers that are ectoderm, endoderm, and mesoderm are formed during gastrulation. During gastrulation, the blastoderm splits into two layers: an upper layer of cells called epiblast and a lower layer of cells called hypoblast. The epiblast is the presumptive ectoderm and mesoderm while the hypoblast is the presumptive endoderm.
