Mantle layer

Vedclass · Answer

(C) The pearl is secreted by the mantle layer of the mollusk.The mantle is a specialized tissue that secretes the shell components.When a foreign particle (like a parasite or sand grain) enters between the mantle and the shell,the mantle cells secrete layers of nacre (calcium carbonate and conchiolin) around the irritant to protect the soft body of the mollusk,eventually forming a pearl.Therefore,the mantle is the primary organ responsible for the secretion of the pearl.
