Question

Quizplus · Accepted Answer

Cones are responsible for color vision and visual acuity, and they are highly concentrated in the fovea, which is the central part of the retina where images are focused. The fovea contains no rods, which are more sensitive to light but have lower visual acuity than cones. Ganglion cells and bipolar cells are involved in transmitting visual information to the brain but they do not contribute directly to visual acuity.
