Question

The light-sensitive cells found on the retina are known as:

• A. Rods and cones
• B. Iris and pupil
• C. Cochlea and pinna
• D. Vitreous and aqueous humour

Answer 1

The correct option is A

Rods and cones

Rods and cones are the light-sensitive cells on the retina. Cones are sensitive to bright light and are capable of colour vision. Rods are sensitive to dim light and give twilight vision. They convert light waves into electrical impulses which are read by the brain.
