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

  1. Schizocoelomate
  2. Spongocoelomate
  3. Acoelomate
  4. Pseudocoelomate

Answer

(4) Pseudocoelomate

Solution

As per NCERT, a body cavity lined by mesoderm is a true coelom (coelomates, e.g. annelids, chordates).

As per NCERT, in some animals the body cavity is not lined by mesoderm; the mesoderm is present only as scattered pouches between the ectoderm and the endoderm. Such a cavity is a pseudocoelom (pseudocoelomates, e.g. aschelminths).

Mesoderm is found towards the body wall but not around the alimentary canal, so the cavity is not fully lined by mesoderm.

The animal is a pseudocoelomate.

Acoelomates (e.g. platyhelminthes) have no body cavity at all, and schizocoelomates have a true coelom.
