Question

While trying to find out the characteristic of a newly found animal, a researcher did the histology of 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?

पर्याय

• Acoelomate

• Pseudocoelomate

• Schizocoelomate

• Spongocoelomate

Answer 1

Pseudocoelomate

Explanation:

The animal in the scenario has mesodermal tissue along the body wall but not around the alimentary canal, suggesting that mesoderm does not completely line the body cavity. This is a feature of a pseudocoelom, which is present in creatures such as roundworms. While acoelomates have no body cavity at all, true coelomates (schizocoelomates or enterocoelomates) have a cavity that is entirely walled by mesoderm.
