Question

Choose the correct answers from the alternatives given.
When an earthworm secretes a slime layer to receive eggs and sperm and form a cocoon, this secretion is produced by the:

• A. peritoneum
• B. clitellum
• C. nephridium
• D. prostomium

Answer 1

The correct option is B clitellum

The clitellum is a thick, saddle-like ring found in the epidermis (skin) of the worm, usually with a light-coloured pigment. To form a cocoon for its eggs, the clitellum secretes a viscous fluid. This organ is used in sexual reproduction of some annelids such as earthworms.

So, the correct option is, 'clitellum'.
