Answer
They are concentrated mainly in the fovea centralis.**Explanation:**Rod cells are responsible for vision in low light conditions, motion detection, and peripheral vision. While highly sensitive to light, they do *not* provide sharp vision or color perception. The fovea centralis, the area of the retina responsible for sharp central vision, is densely packed with *cones*, not rods. Rods are more concentrated in the peripheral regions of the retina.
