Q. Which one of the following structures in Pheretima is correctly matched with its function?
A) Setae-defence against predators
B) Typhlosole - storage of extra nutrients
C) Clitellum - secretes cocoon
D) Gizzard - absorbs digested food
Explanation
[Solution from source] The clitellum of Pheretima secretes the cocoon in which the eggs are deposited. Setae help in locomotion, the typhlosole increases the absorptive area of the intestine, and the gizzard grinds food rather than absorbing it. Answer (3).
