The term 'SITE FOR RODS AND CONES' can be summarized as the RETINA, which is a 6-letter word. The RETINA is a light-sensitive layer of tissue located at the back of the eye that contains both rods and cones. Rods are responsible for vision in dim light, while cones are responsible for color vision and detail vision in bright light. The RETINA is essential for vision, as it converts light into electrical signals that are sent to the brain.
