NEET · Biology · STD 11 - 4. Animal kingdom
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 coelome of that animal?
- A Acoelomate
- B Pseudocoelomate
- C Schizocoelomate
- D Spongocoelomate
Answer & Solution
Correct Answer
(B) Pseudocoelomate
Step-by-step Solution
Detailed explanation
In pseudocoelomates, the body cavity is not entirely lined with mesoderm, instead, mesodermal tissue is present along the body wall but not towards the gut.
- Schizocoelomates are animals whose coelom or body cavity develops middle from a split in the mesoderm, the middle germ layer of the embryo.
- In acoelomates, coelom is absent.
Spongocoel is a central cavity found in Sponges.
- Schizocoelomates are animals whose coelom or body cavity develops middle from a split in the mesoderm, the middle germ layer of the embryo.
- In acoelomates, coelom is absent.
Spongocoel is a central cavity found in Sponges.
