Vedclass · Answer

(A) The correct answer is $A$.$1$. Rod cells are photoreceptor cells in the retina that contain the pigment rhodopsin. They are highly sensitive to light and are essential for vision in dim light (scotopic vision).$2$. Cone cells are photoreceptor cells responsible for colour vision and high-resolution (detailed) vision in bright light (photopic vision). They contain the pigment iodopsin.$3$. Regarding option $A$: Rod cells function in poor light,while cone cells are specialized for colour and detailed vision in bright light. This is the correct functional distinction.$4$. Option $B$ is incorrect because cone cells are concentrated in the fovea (centre of the retina),while rods are more abundant in the periphery.$5$. Option $C$ is incorrect because cones provide high visual acuity,whereas rods provide low visual acuity.$6$. Option $D$ is incorrect because rods contain rhodopsin and cones contain iodopsin,making the order reversed.
