Question:medium
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?

Show Hint
Pseudocoelomates have a body cavity that is partially lined with mesoderm, unlike coelomates where the entire cavity is surrounded by mesoderm. This structural difference is important in classifying animals.

- Pseudocoelomate
- Schizocoelomate
- Spongocoelomate
- Acoelomate
Hide Solution
The Correct Option is A
Solution and Explanation
Coeloms in animals are body cavities lined by mesodermal tissue. A characteristic of pseudocoelomates is having mesodermal tissue present only toward the body wall, not the alimentary canal. Unlike true coelomates, pseudocoelomates possess a body cavity (pseudocoel) that is not entirely enclosed by mesodermal tissue. Therefore, Pseudocoelomate is the correct classification.
