Answer 1

Cones are cone shaped structures and are required for bright light (day light) vision. Rods are rod like structures and are required for dim light (twilight/ night) vision. Both rods and cones contain light sensitive pigments. Rod cells contain a purplish pigment known as visual purple or rhodopsin and it is formed from vitamin A.

Rods

Photoreceptors in the retina are classified into two groups, named after their physical morphologies. Rod cells are highly sensitive to light and function in nightvision.

Cones
