There are about 120 million rods in the human eye and about 6 million cones. This is the main difference between the two types of cells. Rods are more sensitive to light and are used for night vision, while cones are responsible for color vision and require higher light levels to function well. Option A is incorrect as it is the opposite of what is true, Option B is incorrect because the fovea has a higher concentration of cones rather than rods, and Option D is incorrect since there are significant differences in function between the two types of cells.
