Many parts of the eye work to focus or control light except the(1 point)
Responses
A. cornea.
B. pupil.
C. lens.
D. retina.
To find the correct answer, we need to identify the part of the eye that does not work to focus or control light. We can achieve this by understanding the function of each of the given options.
A. Cornea: The cornea is the clear, outermost layer of the eye that refracts light and helps to focus it onto the retina. So, the cornea does work to focus or control light.
B. Pupil: The pupil is a small opening in the center of the iris that regulates the amount of light entering the eye. It adjusts in size to control the amount of light reaching the retina. Therefore, the pupil does work to control light.
C. Lens: The lens is a flexible, transparent structure located behind the iris. It adjusts its shape to focus light onto the retina, allowing us to see objects clearly at different distances. Hence, the lens also plays a role in focusing light.
D. Retina: The retina is a layer of light-sensitive tissue at the back of the eye. It contains photoreceptor cells that convert light into electrical signals, which are then transmitted to the brain for visual processing. The retina does not actively focus or control light itself.
Based on this analysis, we can conclude that the correct answer is D. retina, as it does not work to focus or control light.
