Explain the following:
Mechanism of generation of light-induced impulse in the retina.

Explanation

### Step-by-Step Solution:

1. **Understanding Photoreceptor Cells**:
- The retina contains specialized cells known as photoreceptors, which are of two types: rod cells and cone cells. Rod cells are responsible for vision in low light, while cone cells are responsible for color vision and function best in bright light.

2. **Light Induction**:
- When light enters the eye, it induces a chemical change in the photoreceptor cells. Specifically, light causes the breakdown of a pigment called retinal, which is a component of the photopigment found in these cells.
