(iv) The rods contain a purplish-red protein called the rhodopsin, which contains a derivative of vitamin-A

(v) In the human eye, there are three types of cones which possess their own characteristic photo pigments that respond to red, green and yellow lights.

(vi) Photoreceptor cells are not present in blind spot.
