The colour of light not utilized during photosythesis is

Options

A. Violet
B. Green
C. Red
D. Blue

Answer

To determine the color of light that is not utilized during photosynthesis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy, using chlorophyll to absorb light.

2. **Identifying Light Colors**: The visible spectrum of light includes various colors: red, orange, yellow, green, blue, indigo, and violet.

3. **Role of Chlorophyll**: Chlorophyll is the primary pigment involved in photosynthesis. It absorbs light most effectively in the blue and red wavelengths.

4. **Green Light Absorption**: Chlorophyll reflects and transmits green light rather than absorbing it. This means that green light is not effectively utilized in the photosynthesis process.

5. **Conclusion**: Since green light is reflected and not absorbed, it is the color of light that is least utilized during photosynthesis.

### Final Answer:
The color of light not utilized during photosynthesis is **green**.
