Answer and Explanation:
By observing an object in an almost dark place and then observing the same object in a bright environment through peripheral vision, it is possible to understand more clearly the functions of rods and cones.
Cones and rods are two types of cells present in the retina and very important for vision. The rods allow us to be able to see in low light environments. Therefore, when we look at an object in an almost dark place, we are able to define the shape and what the object is, even if we cannot see the details of the object. This happens thanks to the rods, however, as the environment does not have much light, we do not see the colors of the object with much definition.
On the other hand, the cones are responsible for the visualization of colors and it is because of the cones that we are able to observe the colors of objects that are outside our focus of vision, that is, that are being observed by our peripheral vision, as long as there is light in the environment to reflect the colors.
