Question

The archenteron develops into ______.

Options

• blastocoel

• endoderm

• lumen of the digestive tract

• placenta

Answer 1

The archenteron develops into lumen of the digestive tract.

Explanation:

The archenteron is the primitive gut formed during gastrulation and it eventually develops into the lumen of the digestive tract. It is a cavity lined by endodermal cells, which gives rise to the internal space of the digestive system. It does not develop into the blastocoel, endoderm (the layer itself), or placenta directly.
