Question

Classify the following organism based on the absence/presence of true coelom.

Earthworm

• A. Coelomate
• B. Acoelomate
• C. Pseudocoelomate
• D. Heterocoelomate

Answer 1

The correct option is A Coelomate

• Earthworm belongs to phylum Annelida with metameric segmentation in the body.
• They possess a true body cavity. Hence, they are coelomate.
• The coelom is the body cavity between the mesoderm and endoderm layer.
• A coelom can absorb shock or provide a hydrostatic skeleton.
• The coelom allows muscles to grow independently of the body wall.

So, the correct answer is option A.
