Final answer:
The retina is composed of several layers and one of these layers is made up of light-sensitive cells called rods and cones. Rods are more sensitive than cones and are responsible for peripheral vision and vision in dim light, while cones are responsible for color vision.
Step-by-step explanation:
The retina is composed of several layers and contains specialized cells for the initial processing of visual stimuli. One of these layers is made up of light-sensitive cells called rods and cones. Rods are more sensitive than cones and are responsible for peripheral vision and vision in dim light, while cones are responsible for color vision.
