Final answer:

Rods and cones are the two types of photoreceptors in the human retina. Rods are more sensitive to light and are primarily responsible for peripheral and nighttime vision. Cones are responsible for color vision and high resolution vision.

Step-by-step explanation:

Rods and cones are the two types of photoreceptors in the human retina. Rods are more sensitive to light and are primarily responsible for peripheral and nighttime vision. There are approximately 120 million rods in the human retina, and they are found throughout the entire retina with a higher concentration towards the periphery. On the other hand, cones are responsible for color vision and high resolution vision. There are approximately 6 million cones in the human retina, and they are predominantly found in the central portion of the retina, particularly in the fovea.
