14. The light sensitive cells of the eye are called rods and cones. In which of these layers of the eye are they found?
Answer: D
The light sensitive cells of the eye are found in the retina.
The light sensitive cells known as rods and cones are located in the retina, which is the innermost layer of the eye responsible for converting light into neural signals.
A) Choroid
The choroid is a layer of the eye situated between the retina and the sclera. It is primarily composed of blood vessels and connective tissue, serving to nourish the retina but does not contain the light sensitive cells themselves.
B) Sclera
The sclera is the white outer layer of the eye that provides structural support and protection. It does not contain rods and cones; instead, it acts as a protective covering for the inner components of the eye.
C) Cornea
The cornea is the transparent front part of the eye that covers the iris and pupil. While it plays a critical role in focusing light onto the retina, it does not contain any light sensitive cells such as rods or cones.
D) Retina
The retina is the correct answer as it is the layer of the eye that contains the light sensitive cells known as rods and cones. These cells are crucial for vision, allowing the eye to detect light and color.
Conclusion
The retina is the only layer among the options provided that houses the light sensitive cells, rods and cones, which are essential for vision. The other options—choroid, sclera, and cornea—do not contain these cells and serve different functions in the eye's anatomy. Thus, the retina is definitively the correct answer.
