Question

The cavity, which formed during gastrulation is named as

• A. Blastocoel
• B. Archenteron
• C. Coelom
• D. Pseudocoel

Answer 1

The correct option is B Archenteron

• Blastocoel is the fluid-filled central region in blastula.
• Archenteron is the cavity within an embryo at the gastrula stage of development, which eventually becomes the digestive cavity.
• The coelom is the body cavity which is lined by epithelium-derived from mesoderm.
• Pseudocoel is a body cavity, that is not a product of gastrulation and is not lined with a well-defined mesodermal membrane.

So, the correct answer is option B.
