Question

Quizplus · Accepted Answer

Cones and rods are the two types of photoreceptor cells in the retina. Cones are responsible for color vision and detailed vision in bright light, while rods are responsible for vision in low light conditions. Cones are more densely concentrated in the fovea centralis, which is the area of the retina responsible for high-acuity vision. Rods are more densely concentrated in the peripheral regions of the retina, allowing for better detection of dim light in the periphery. Therefore, statement B is correct - cones are most densely concentrated in the fovea centralis.
