Quizplus · Accepted Answer

The main function of rods and cones is to turn light into neural signals that can be transmitted to the brain for processing and interpretation, allowing us to see. This process involves the conversion of light energy into electrochemical signals that the nervous system can use to create a visual experience. Therefore, choice D, "turn light into an energy useable by the nervous system," is the best choice.
