Question

What is the name of the fibres in the eyes, that sense colour?

• A. Retina
• B. Pupil
• C. Rods and cones
• D. None of these

Hint:

Cones in the retina enable color vision, with three types detecting red, green, and blue wavelengths, while rods handle low-light vision.

Answer 1

The Correct Option is C

Explaining eye anatomy
Step 1: The human eye contains specialized cells in the retina responsible for sensing light and color.
Identifying color
-sensing cells
Step 2: The retina contains two types of photoreceptor cells: rods, which detect light intensity and function in low
-light conditions, and cones, which detect color. Cones are responsible for color vision, with three types sensitive to red, green, and blue light.
Evaluating options
Step 3: Analyze the options:
- (A) Retina: Incorrect, as the retina is the layer containing the cells, not the cells themselves.
- (B) Pupil: Incorrect, as the pupil is the opening that controls light entry, not a sensing structure.
- (C) Rods and cones: Correct, as cones specifically sense color, and rods and cones are the photoreceptor cells.
- (D) None of these: Incorrect, as rods and cones are the correct answer.
Thus, the correct answer is (C).
