Question

Choose the correct answer from each of the four options given below:

The part of the human eye where rod and cone cells are located of

• A. Retina
• B. Cornea
• C. Choroid
• D. Sclera

Answer 1

The correct option is A

Retina

The correct option is (A)

Explanation of correct option:

1. Rods and cones are photoreceptors or photosensitive cells (they respond to light).
2. Whenever light falls on these cells, there are chemical changes in these cells, and due to the changes, there is a perception of vision.
3. So, they must be present in the layer of the eye which is responsible for the vision.
4. The different layers of the eye from the outside to the inside are the sclera after that choroid, and the innermost layer present in the eye is the retina.
5. The retina contains the rods and cones.

Explanation of an incorrect option:

Option (B): Cornea:

1. It is a part of the Sclera, which is the outermost layer.
2. It is a transparent layer that is present in front of the eye, and it is responsible for the passage of light.
3. Like it allows light to be transmitted inside the eye so we can see.

Option (C): Choroid:

1. The choroid is the middle layer of the eye, and it is a highly vascular structure (there are lots of blood vessels present).
2. It is generally responsible for the holding of lenses, and it is also forming the Iris, which is the colorful portion of the eye.

Option (D): Sclera: The outermost layer of the eye which is responsible for the protection of the eye.

Final Answer:

The photoreceptor cells of the retina sensitive to color are Retina.
