Answer 1

The purpose of photoreceptors is to detect and respond to light. They are specialized cells found in the retina of the eye and play a crucial role in vision. When light enters the eye and reaches the retina, photoreceptor cells convert the light into electrical signals, which are then sent to the brain for processing. The different types of photoreceptors, called cones and rods, are responsible for different aspects of visual perception, such as color vision, sharpness of detail, and sensitivity to dim light. Overall, the purpose of photoreceptors is to enable organisms to visually perceive their environment.
