Question

Coelenterata is acoelomate or coelomate?

Answer 1

• It is a well known fact that the Coelomate is equipped with body cavity without the presence of mesoderm in the germ layer.

• You will not find genuine internal coelom, therefore it is not considered coelomate.

In real world organism differentiated organs can be accommodated without any problem.

Answer 2

It is believed that coelenterata have coelom, but they have only two layers of cells: one makes up cells on outside the body, and other makes the inner lining of body. Which could not form any genuine internal coelom, therefore it is not considered as coelomate. It is acoelomate.
