which photoreceptor cells respond to very dim light?

○ bipolar cells
○ ganglion cells
○ rods
○ cones

Explanation:

To determine which photoreceptor cells respond to very dim light, we analyze each option:

• Bipolar cells: These are not photoreceptor cells; they are neurons that transmit signals from photoreceptors to ganglion cells.
• Ganglion cells: These are also not photoreceptor cells; they receive signals from bipolar cells and send them to the brain.
• Rods: Rods are photoreceptor cells specialized for vision in low - light (dim) conditions. They are more sensitive to dim light compared to cones.
• Cones: Cones are photoreceptor cells that are responsible for color vision and function best in bright light.

So, the photoreceptor cells that respond to very dim light are rods.

Answer:

C. rods
