What is the origin of the acoelomate gut?
Correct answer: C. Endodermal
- A. Ectodermal
- B. Mesodermal
- C. Endodermal
- D. None of these
Explanation
The endoderm is the innermost primary germ layer, and it is the one responsible for giving rise to the epithelial lining of the digestive tract, respiratory system, and several other internal organs. The gut is derived from the endoderm during embryonic development. In acoelomates (a group of animals without a body cavity called a coelom), the gut lacks a coelom and maintains a solid, simple structure.
