### Step-by-Step Solution: 1. **Definition of Rods and Cones**: - Rods and cones are types of photoreceptor cells located in the retina of the eye. They are responsible for converting light into neural signals that can be processed by the brain. 2. **Function of Rods**: - Rods are primarily responsible for vision in low-light conditions (dim light). They contain a photopigment called rhodopsin, which is sensitive to light. - Rods enable night vision (scotopic vision) and are more sensitive to light than cones, allowing us to see in darker environments. ...
