Parts A, B, C and D of the human eye are shown in the diagram. Select the option which gives correct identification along with its functions/characteristics:

1. B-Blind spot-has only a few rods and cones
2. C-Aqueous chamber-reflects the light which does not pass through the lens.
3. D-Choroid-its anterior part forms ciliary body
4. A-Retina-contains photoreceptors-rods and cones.

Correct answer: A-Retina-contains photoreceptors-rods and cones.

Solution

The retina is the light-sensitive inner layer of the eye and contains the photoreceptors rods and cones. These cells convert light into nerve impulses, so the option identifying A as the retina is correct.
