Question

What type of exoskeleton do some molluscs present?

asked Jan 5, 2022 by anonymous

1 Answer

Answer :

Some molluscs, like bivalves and gastropods, secrete an external calcareous carapace (the shell). Calcium carbonate is secreted by the mantle, a fold in the epidermis, forming the shell. In pelecypods, the shell is made of two valves that articulate and contain the individual body within. In gastropods the shell contains only part of the body, the visceral mass.

What is the type of digestive system in molluscs?

Description : What is the type of digestive system in molluscs?

Last Answer : Molluscs present extracellular digestion and a complete digestive system, with mouth and anus.

Mechanical digestion is the fragmentation of food aided by specialized physical structures, such as teeth, previous to extracellullar digestion. The mechanical fragmentation of food helps digestive enzymatic reactions because it provides a larger total area for the contact between enzymes and their substrates. In some molluscs, the mechanical fragmentation is done by the radula (a teeth-like structure). Some arthropods, like lobsters and dragonflies, have mouthparts that make mechanical digestion of food. In earthworms and birds, the mechanical digestion is made by an internal muscular organ. In mandibulate vertebrates there are mandibles and chewing muscles to triturate food previous to the chemical digestion.
