Question
What type of photoreceptor is more sensitive to light and can, therefore, provide vision in dim light?
- Multiple Choice:
- Rods
- Cones
Solution
Answer
The type of photoreceptor that is more sensitive to light and provides vision in dim light is Rods.
Explanation
Rods are photoreceptor cells located in the retina of the eye that are highly sensitive to low levels of light, making them essential for night vision. They contain a pigment called rhodopsin, which enables them to detect light in low-light conditions. Unlike cones, which are responsible for color vision and function best in bright light, rods do not provide color information but are adept at detecting motion and shape in dim environments. This makes them crucial for night-time and low-light vision.
