Final answer:
The structure of the eye that contains the photoreceptors, rods and cones, is the D.retina.
Step-by-step explanation:
The structure of the eye that contains the photoreceptors (rods and cones) is the D. retina.
The retina is the innermost layer and part of the neural tunic, containing nervous tissue responsible for photoreception.
Specialized cells within the retina, known as cones, are highly sensitive to light and are responsible for our ability to perceive color and detail, and are densely packed in the fovea.
Rod cells are also found in the retina and are adapted for vision in dim light, allowing us to see shades of gray.
Light entering the eye first passes through the cornea and then the pupil, after which it is focussed by the lens onto the retina.
The retina converts the light signals into electrical impulses that are sent to the brain via the optic nerve, enabling us to see.
