What are rods and cones?

Answer 1

Rods and cones are photoreceptors in the eye that allow people to see. Rods allow people to see colors, while cones allow people to see in low light, and in great detail.

Answer 2

Rods & cones are special cells in the retina that are responsible for vision. They react to light energy by a change in the configuration of visual pigments and convert the light energy to electrical energy. This results in the depolarization of the cells and other cells down the line up to the retinal ganglion cells. These cells in turn transmit the stimulus to the brain through the optic nerve. Rods are rod shaped cells responsible for dim light vision & black and white vision. Cones are cone shaped cells responsible for acuity of vision, bright light vision and color vision

The retina contains two types of photoreceptors, rods and cones. The rods are more numerous, some 120 million, and are more sensitive than the cones. However, they are not sensitive to color. The 6 to 7 million cones provide the eye's color sensitivity and they are much more concentrated in the central yellow spot known as the macula. In the center of that region is the " fovea centralis ", a 0.3 mm diameter rod-free area with very thin, densely packed cones. Rods are sensitive to light (shades of light), and Cones are sensitive to color

Answer 3

Rods and cones are photoreceptor cells in the retina of the eye that detect light. Rods are responsible for vision in low light conditions and detecting motion, while cones are responsible for color vision and detailed visual acuity in bright light.

Answer 4

Rods and cones are photoreceptors in the eye that allow people to see. Rods allow people to see colors, while cones allow people to see in low light, and in great detail.
