Quizplus · Accepted Answer

Rods are responsible for vision in low light conditions, such as at night. They are more sensitive to light than cones, the other type of photoreceptor in the retina, but do not differentiate between colors. They are found throughout the retina, but are more concentrated in the periphery rather than the fovea, which is dominated by cones.
