NEET (UG) 2025 — Question 102
While trying to find out the characteristic of a newly found animal, a researcher performed a histological examination of the adult animal and observed a cavity with presence of mesodermal tissue towards the body wall, but no mesodermal tissue was observed towards the alimentary canal. What could be the possible coelom of that animal?
- Option A:
Acoelomate
- Option B:Correct
Pseudocoelomate
- Option C:
Schizocoelomate
- Option D:
Spongocoelomate
Answer: B
Step-by-step solution
A pseudocoelom is a body cavity that is not completely lined by mesoderm. In pseudocoelomates, mesoderm lines the body wall but is absent around the alimentary canal. The observed histology matches exactly this condition. Hence the cavity is a pseudocoelom, and the animal is a pseudocoelomate. Correct option is B.
