Question

Consider the following statements:
Statement 1: Cone cells are sensitive to dim light.
Statement 2: Rod cells are sensitive to bright light.

Choose the correct option:

• A. Parallel to the incident rays
• B. Parallel to each other
• C. Inclined to each other
• D. Opposite to the incident rays

Answer 1

The correct option is D

Opposite to the incident rays

There are two kinds of sensitive cells present in the retina:

(i) Cones, which are sensitive to bright light and
(ii) Rods, which are sensitive to dim light.
Besides, cones are sensitive to colour.

Thus, both the statements in the question are incorrect.
