Question

Schizocoelomates and enterocoelomates are

• A. acoelomates
• B. invertebrates
• C. true coelomates
• D. echinoderms only

Answer 1

The correct option is C true coelomates

Coelom is located between the intestinal canal and the body wall. It is lined by mesoderm. Animals possessing coelom are called coelomates. In some animals, the body cavity is not lined by mesoderm, instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Such a body cavity is called pseudocoelom and the animals possessing them are called pseudocoelomates.

Schizocoelomates are invertebrate animals that possesses a schizocoel, a coelom, which is formed by the splitting of the mesodermal cells.

Enterocoelomates are animals in which the coelom is lined by mesoderm, which arises in the embryonic stage as an outpocketing of the developing gut.

Hence, schizocoelomates and enterocoelomates are true coelomates.
