Final answer:
Rods and cones are two types of photoreceptors in the retina with different functions. Rods are specialized for low light conditions and provide peripheral and nighttime vision. Cones are responsible for color vision and have better spatial resolution than rods.
Step-by-step explanation:
Rods and cones are two types of photoreceptors in the retina that play different roles in vision. Rods are located throughout the retina, except for the fovea, and are specialized for low light conditions. They provide us with peripheral and nighttime vision, but lack color sensitivity and spatial resolution. On the other hand, cones are concentrated in the fovea and are responsible for color vision in intense light. They have better spatial resolution than rods and are important for daytime vision.
