Question

Mention the functions of Radula

Answer 1

The radula helps to graze upon microscopic filamentous algae from a surface and feed directly on plants. It is like a chitinous ribbon and is used for scrapping and cutting food before it enters the oesophagus. The teeth on the membrane are called denticles and are constantly shed and regrown.

Answer 2

$\huge\mathfrak\red{Answer}$

★The radula can be adapted to a number of harvesting techniques, from using the teeth for boring holes into the shells of other animals for consumption, or for grazing on algae and other minute plant life.

★The radula can function either as a rake to scoop food into the mouth, or as a means to latch onto a plant or other food source for direct feeding.

★The radula is the shellfish's only means of consuming food, and plays a pivotal role in the survival of the animal.
