Which statement about the retina is true?

• A. It uses rods and cones and is the most sensitive structure
• B. It is the transparent front layer of the eye
• C. It is responsible for focusing light onto the retina
• D. It forms the black center of the eye

Answer: (A)

Photoreception happens in the retina, the light-sensitive layer at the back of the eye. It contains the photoreceptor cells called rods and cones. Rods are highly sensitive to low light and help with night vision, while cones detect color and fine detail in brighter light. Because the retina is the tissue that directly detects light and converts it into neural signals, the statement that it uses rods and cones and is the most sensitive structure is true. The transparent front layer of the eye is the cornea, not the retina. Focusing light onto the retina is mainly the job of the cornea and the lens, not the retina itself. The black center of the eye is the pupil, which is the opening that lets light in, not a retinal structure.
