Question

Nutritive substance for cocoon secreted by

• A. Mucous cells
• B. Albuminous cells
• C. Yellow cells
• D. All of these

Answer 1

The correct option is A Mucous cells

The clitellum plays an important role in reproduction. Its glands produce mucous which becomes a sheath containing nutritive material. The sheath slides forwards, collecting eggs and sperm from the genital openings of the worm. The sheath finally slides off from the head of the worm. As it separates from the worm, its ends are sealed. It now becomes a cocoon.

So, the correct option is 'Mucous cells'.
