Which of the following pairs is correct?
1 annelida-polychaeta-leech
2 arthropoda-crustacea-cockroach
3 mollusca-cephalopoda-Octopus
4 protozoa-Hydra
Explanation:
C Cephalopoda is a class of pylum Mollusca. - Head and foot regions are combined and modified into a structure which has eyes and eight tentacles, hence the name cephalopod or 'head food'. - Octopus belongs to this class

In Mollusca, eye is present over a stalk, called
1 ostracum
2 operculum
3 ommatophores
4 osphradium
Explanation:
C The ommatophores of crustaceans are called ophthalmites. The eye stalk which is a protrusion extending the eye in mollusca away from the body is known as Ommatophore. It appears like a stumpy peduncle, on which eyes are located in molluscs. This is helpful in providing a better field of vision to the organisms such as snails (molluscs). Molluscs have eyes varying from simple structure to complexier ones.

Osphradium of Pila globosa is:
1 photoreceptor
2 chemoreceptor
3 thermoreceptor
4 tangoreceptor
Explanation:
B Osphradium of Pila globosa is a chemoreceptor. It helps to detect the chemical composition of water. It is located in the mantle cavity of the snail and is a small, finger. like structure osphradium has a patch of sensory cells which helpful in detection of food, avoiding predators and selection of suitable habitat. - The retina contain sensitive cells called photoreceptors. - Thermoreceptor responsible for changes in temperature. - Tangoreceptor are stimulated by touch and pressure.
