Type of body cavity (Coelom) in earthworm is :-[BHU - 87]a)Acoelomicb)...
Type of Body Cavity (Coelom) in Earthworm is Schizocoel.
Explanation:
- Coelom is a fluid-filled body cavity that is lined by mesoderm.
- Three types of coelomates are found in the animal kingdom, based on the formation of coelom:
- Schizocoelous
- Enterocoelous
- Pseudocoelous
- In Schizocoelous coelom formation, the mesoderm splits to form the coelom.
- Earthworm is an example of Schizocoelous coelomate.
- In earthworm, the mesoderm splits into two layers:
- Outer layer: forms the body wall
- Inner layer: forms the mesentery that suspends the internal organs within the coelom.
- The coelomic space is divided into several compartments by transverse septa.
- Earthworm's coelomic cavity acts as a hydrostatic skeleton, providing support against the surrounding soil.
- It also serves as a circulatory system, carrying blood and nutrients to various parts of the body.
- The coelomic fluid aids in respiration, waste removal, and maintaining the water balance in the body.
- Earthworm's coelom is also involved in reproduction, as it houses the reproductive organs.
Therefore, the correct answer is option B, i.e., Schizocoel.
