Final answer:
The photoreceptors involved in noncolor vision are rods, while cones are responsible for color vision and visual acuity. Rods operate in low light and detect shades of gray, whereas cones function in brighter light, enabling color perception and detailed vision.
Step-by-step explanation:
The photoreceptors that are involved in noncolor vision are rods, and the cones are photoreceptors that are involved in color vision and visual acuity. Thus, the correct answer is A) Rods, cones.
The rods are highly sensitive to light, allowing us to see in low-light conditions, but can only detect shades of gray. On the other hand, cones require more light and are responsible for our ability to see fine detail and color. Cones exist in three forms (L, M, and S), each differentially sensitive to various wavelengths of light, contributing to our perception of color. While rods are abundant in the peripheral regions of the retina, the cones predominate in the fovea, the central area of the retina where visual acuity is highest.
