Based on the scenario provided, identify the visual system and the primary type of light-sensitive cell being used, and explain why they are active in this situation.

Visual Processing in Bright Light

Based on the scenario provided, explain which visual system is primarily engaged and which specific light-sensitive cells are responsible for the experience described. Justify your answer by connecting the details of the scenario to the functions of the system and cells.

Visual System in Action

- System used by the eye when there are high levels of light
- Uses cones, so it can detect color

There are two types of photoreceptors in the eye: rods and cones. They are light-sensitive receptors. Rods are most active when there is dim lighting. Cones are most active when there is bright lighting, and can detect color.
