Q14 / 180 · NEET 2025 · Botany

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
  • Correct answer
    B
    Pseudocoelomate
  • C
    Schizocoelomate
  • D
    Spongocoelomate

Solution

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.

Hence, the correct answer is option: 'B'.
