Which light is a absorbed more by carotenoids ?

Options

A. Yellow and green region
B. Blue - green and violet region
C. Yellow and orange - red region
D. yellow and blue - green region

Answer

To determine which light is absorbed more by carotenoids, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Carotenoids**:
- Carotenoids are pigments found in plants, algae, and some bacteria. They are responsible for the yellow, orange, and red colors in many fruits and vegetables.

2. **Light Absorption**:
- Carotenoids absorb specific wavelengths of light for photosynthesis. The absorption spectrum of carotenoids indicates which wavelengths they are most effective at absorbing.

3. **Identifying Absorbed Wavelengths**:
- Research shows that carotenoids primarily absorb light in the blue-green (around 450-500 nm) and violet (around 400-450 nm) regions of the light spectrum.

4. **Reflecting Wavelengths**:
- Carotenoids reflect longer wavelengths, which correspond to yellow, orange, and red light. This reflection is why they appear in those colors.

5. **Conclusion**:
- Therefore, the light that is absorbed more by carotenoids is in the blue-green and violet regions.

### Final Answer:
Carotenoids absorb more light in the **blue-green and violet regions**.
