AP PSYCHOLOGY

Detailed explanation-1: -These specialized cells are called photoreceptors . There are 2 types of photoreceptors in the retina: rods and cones . The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision.

Detailed explanation-2: -The two types of photoreceptors in the eye are rods for black and white vision and cones for color vision. Rods are more active during periods of low ambient light, while cones are more active during periods of higher ambient light.

Detailed explanation-3: -Rods are responsible for peripheral vision, and are located outside of the central part of the retina. There are some 120 million of them, and they are responsible for night vision, because they are highly sensitive to low-intensity light.

Detailed explanation-4: -Rods are a type of photoreceptor cell present in the retina that transmits low-light vision and is most responsible for the neural transmission of nighttime sight. Rods have a singular photopigment, rhodopsin, which utilizes the protein scotopsin and the Vitamin A-derived cofactor, retinol.

Detailed explanation-5: -Rod photoreceptors are sensitive in dimly-lit environments, and assist the eye in night vision and seeing in black and white. These photoreceptors contain a protein called rhodopsin (also called visual purple) that provide the eye with pigmentation in low-light conditions.
