What type of membrane lines the back of the eye and functions like camera film?

The retina is the correct answer as it serves a crucial role in the eye by functioning similarly to camera film. This membrane is located at the back of the eye and contains photoreceptor cells known as rods and cones. These cells are responsible for converting light that enters the eye into electrical signals, which are then sent to the brain for interpretation.

When light hits the retina, these photoreceptors respond by initiating a process that leads to the perception of images. This is akin to how camera film captures images when exposed to light. The quality of vision and the ability to detect colors in different lighting conditions depend significantly on the proper functioning of the retina.

In contrast, the cornea is a clear layer that covers the front of the eye and helps focus incoming light but does not function like film. The iris is the colored part of the eye that controls the size of the pupil and helps regulate the amount of light entering the eye, but it does not participate in capturing images. The pupil is the opening at the center of the iris that allows light to enter the eye but is not a membrane at all and does not have imaging capabilities.
