Verified step by step guidance

Understand the function of rod cells: Rod cells are a type of photoreceptor in the retina of the eye. They are highly sensitive to light and are primarily responsible for vision in low-light conditions.

Differentiate between rod cells and cone cells: While rod cells are responsible for night vision, cone cells are responsible for color vision and function best in bright light.

Consider the types of vision: Central vision is mainly associated with the macula and cone cells, which are responsible for detailed and color vision. Peripheral vision involves the outer areas of the retina, where rod cells are more prevalent.

Identify the conditions under which rod cells are most active: Rod cells are most active in dim lighting conditions, making them crucial for night vision.

Conclude the role of rod cells: Based on their sensitivity to low light and their distribution in the retina, rod cells are primarily responsible for night vision, allowing us to see in dark environments.
