Maximum amount of photosynthesis takes place in...... light and minimum amount of photosynthesis take place in ...... light.

Options

A. blue : purple
B. green, purple
C. purple, blue
D. green , red

Explanation

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose. This process primarily occurs in the chlorophyll present in the leaves.

2. **Role of Light in Photosynthesis**: Different wavelengths of light affect the rate of photosynthesis. Plants absorb light primarily in the red and blue wavelengths, while they reflect green light.

3. **Identifying Maximum Photosynthesis**: To determine which light wavelength allows for maximum photosynthesis, we need to look at the absorption spectrum of chlorophyll. Chlorophyll absorbs light most effectively in the blue (around 430-450 nm) and red (around 640-680 nm) regions of the spectrum.

4. **Determining Minimum Photosynthesis**: Since chlorophyll reflects green light (around 500-550 nm), this means that green light is not effectively used for photosynthesis. Therefore, the minimum amount of photosynthesis occurs in green light.

5. **Final Answer**: Based on the analysis, we conclude that:
- Maximum amount of photosynthesis takes place in **blue light**.
- Minimum amount of photosynthesis takes place in **green light**.

### Final Answer:
- Maximum amount of photosynthesis takes place in **blue light**.
- Minimum amount of photosynthesis takes place in **green light**.
