Final answer:
The photoreceptors that enable us to see in dimly lit rooms, at twilight, or in pale moonlight are called rods. Rods are strongly photosensitive and specialized for peripheral and nighttime vision.
Step-by-step explanation:
The photoreceptors that enable us to see in dimly lit rooms, at twilight, or in pale moonlight are called rods.
Rods are one of the two major types of photoreceptor cells found in the retina. They are strongly photosensitive and are responsible for detecting dim light. Unlike cones, which are responsible for color vision and function best in bright light, rods are specialized for peripheral and nighttime vision.
For example, when you enter a dark movie theater, you initially have difficulty seeing. As your eyes adjust to the darkness, the rod activity increases, allowing you to see in low-light conditions. However, rods do not provide color information, so your vision becomes less colorful in dim light.
