Answer:
Rods.
Explanation:
There are two types of photoreceptor cells, the cones, and the rods.
The cones adapt our vision to bright light and allow us to see colors. On the other hand, rods photoreceptors make us see in the dark and do not perceive many colors; that is why we can not distinguish colors in the dark. Also, they provide peripheral vision since they are on the external edges of the retina.
