Question

Quizplus · Accepted Answer

Rods are more sensitive to light than cones and are responsible for vision in low light conditions. Cones, on the other hand, are responsible for color vision and are more sensitive to bright light. Therefore, A is incorrect. While rods are good at detecting fine details, cones are better at detecting high spatial frequency patterns, making B incorrect. Rods are actually more numerous than cones in the retina, making D incorrect. Finally, there are fewer rods than cones in the fovea, which is responsible for high acuity vision, making E also incorrect.
