Question

Which is correctly matched in Pheretima

• A. Clitellum secretes cocoon
• B. Gizzard absorbed digested food
• C. Setae defence against predators
• D. Typhlosole storage of extra nutrients

Answer 1

The correct option is A Clitellum secretes cocoon

Mature sperm and egg cells and nutritive fluid are deposited in
cocoons produced by the gland cells of clitellum. Fertilization and development occur within the cocoons which are deposited in the soil.

The ova (eggs) are fertilized by the sperm cells within the cocoon which then slips off the worm and is deposited in or on the soil. The cocoon holds the worm embryos.

So the correct answer is 'Clitellum secretes cocoon'.
