Question

Coelom produced by splitting of mesoderm is

• A. Enterocoel
• B. Schizocoel
• C. Pseudocoel
• D. None of the above

Answer 1

The correct option is B Schizocoel

A. Enterocoel: Deuterosomes are enterocoeloms. It is formed by fusion of mesoderm lined pouches (pouches of the archentron or primitive gut). For example, Echinodermata and Chordata.

B. Schizocoel: Protostomes are schizocoelous. It is a cavity which develops by splitting the mesodermal layer in embryo. An animal developed from schizocoel is called as schizocoelomate, Eg: Annelids and arthropods.

C. Pseudocoel: It is a false coelom which is not lined by mesoderm. It is connected to archentron.

Hence, coelom produced by splitting of mesoderm is schizocoel. So, the correct answer is 'Schizocoel'.
