| (b) Visual pigment contained : | Iodops | in Rhodpsin |
| (c) Overall function : | Vision in poor light | Colour vision and detailed vision in bright light |
| (d) Distribution : | More concentrated in retina | Evenly distributed all over |

Answer : c
Hints & Solutions
(c) Rod cells is a type of light sensitive receptor cell present in the retinas of vertebrates. Rod contains the pigment rhodopsin and are essential for vision in dim light. Cone cells is a type of light sensitive receptor cell, found in retinas of all diurnal vertebrates. Cones are specialized to transmit information about colour and are responsible for the visual acuity of the eye. They function best in bright light.
