Where are the cones and rods located?

• A. Cornea
• B. Iris
• C. Optic Nerve
• D. Retina

Answer: (D)

Rods and cones are located in the retina, the light-sensitive layer at the back of the eye. These photoreceptor cells detect light and color and convert it into electrical signals that the brain can interpret. Rods are used in low light and for peripheral vision, while cones handle daytime vision and color, with the highest density in the macula and the sharpest vision in the fovea. The cornea is the front surface that helps focus light, the iris controls how much light enters by adjusting the pupil size, and the optic nerve carries visual information from the retina to the brain.
