Answer: The Retina
Step-by-step explanation:
The retina is the innermost layer of the eye, lining the back of the eyeball. It is composed of several layers of nerve cells and other specialized cells, including the photoreceptor cells, which are responsible for sensing light.
There are two types of photoreceptor cells in the retina: rods and cones. Rods are responsible for detecting light in low-light conditions and they are more sensitive to light than cones. Cones, on the other hand, are responsible for detecting light in bright conditions and are responsible for color vision. Both rods and cones detect light by absorbing photons and triggering neural impulses that travel to the brain via the optic nerve.
In summary, the retina, the innermost layer of the eye, contains the photoreceptor cells, rods and cones, which are sensitive to light and allow us to see.
