Final answer:
Rods and cones are two types of retinal photoreceptor cells with different functions. Rods are more sensitive and responsible for peripheral and low-light vision, while cones are responsible for color vision.
Step-by-step explanation:
Rods and cones are two types of retinal photoreceptor cells that have different functions.
Rods are more sensitive than cones and are responsible for peripheral vision, vision in dark environments, and motion detection.
They do not yield color information.
Cones, on the other hand, are less sensitive but are responsible for color vision and are concentrated in the central region of the retina called the fovea.
