Question

Quizplus · Accepted Answer

There are two types of photoreceptors in the retina of the eye: rods and cones. Rods are photoreceptors used for gray-scale (non-color vision) and low light conditions. They contain a chemical called rhodopsin that reacts to light to initiate a local potential. Cones are photoreceptors used for color vision and are responsible for the best visual acuity (sharpest vision). They contain the chemical iodopsin that reacts to light to initiate a local potential. Cones require more light than rods to function.
