Question

Pallium of molluscs is __________.

• A. Thin, non-muscular, non-vascular and glandular
• B. Thick, non-muscular, non-vascular and glandular
• C. Thick, muscular, non-vascular and non-glandular
• D. Thick, muscular, non-vascular and glandular

Answer 1

The correct option is A Thin, non-muscular, non-vascular and glandular

A. Thin, non-muscular, non-vascular and granular

Reason: The mantle also called as pallium (Latin), is an important part of the anatomy of molluscs. It is the dorsal body wall which covers the visceral mass and usually protrudes in the form of flaps well beyond the visceral mass itself. In many species of molluscs, it secretes calcium carbonate and conchiolin, and creates a shell.

So, the correct answer is option A.
