Question

Quizplus · Accepted Answer

Cones have higher acuity than rods because there is little convergence in the cone pathways within the retina. This means that each cone has a direct connection to a single bipolar cell, which in turn connects to a single ganglion cell. As a result, the visual information received by each cone is preserved in the transmission to the brain, resulting in a higher resolution and greater sensitivity to detail. In contrast, rods have a higher degree of convergence, with many rods connecting to a single bipolar cell and many bipolar cells connecting to a single ganglion cell, resulting in lower resolution and less sensitivity to detail. The other choices (A, B, D, and E) are not correct, as they do not accurately explain why cones have higher acuity than rods.
