Rods are the key type of photoreceptor cells in the retina that are primarily responsible for night vision. They are highly sensitive to light and can detect low levels of illumination, which is why they allow us to see in dim light conditions. This sensitivity makes rods particularly effective in low-light environments and facilitates peripheral vision, but they do not convey color information, which is primarily the role of another type of photoreceptor, the cones.

Unlike rods, cones require brighter light to function effectively and are essential for color vision and visual acuity in well-lit environments. The different types of retinal cells, such as retinal ganglion cells and bipolar cells, play roles in processing visual signals but are not directly responsible for capturing light for night vision. Thus, rods are the correct answer as they specialize in creating visual images under low-light conditions.
