Which statement regarding photoreceptors is true?

Question

Quizplus · Accepted Answer

Rods are more sensitive to light than cones. This is because rods contain a visual pigment called rhodopsin, which can detect even small amounts of light, making them more suited for low-light conditions. Cones, on the other hand, require higher levels of light to detect color and detail.

Answer: None of the other options are true.
 Cones are responsible for color vision and are not effective in low-light conditions. Rods, not cones, are found at the greatest density at the periphery of the retina, while cones are more concentrated in the fovea, the center of focus. Finally, rods contain the visual pigment called rhodopsin, not photopsin.
