Options

A. `1 : 1`
B. `5 : 1`
C. `10 : 1`
D. `20 : 1`.

Answer

To solve the question regarding the ratio of carbon dioxide (CO₂) consumption to carbon dioxide production in green plants during the daytime, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photosynthesis and Respiration**:
- During the daytime, green plants primarily engage in photosynthesis, a process that converts carbon dioxide and sunlight into glucose and oxygen. This process consumes CO₂.
- Plants also undergo respiration, which is the process of breaking down glucose to release energy, producing CO₂ as a byproduct.

2. **Stomata Behavior**:
- Stomata are small openings on the leaves that allow gas exchange. During intense sunlight, stomata may close to prevent excessive water loss through transpiration.
- Despite the closure of stomata, photosynthesis continues, leading to a higher consumption of CO₂ compared to the amount produced through respiration.

3. **Ratio of CO₂ Consumption to Production**:
- In the daytime, the rate of CO₂ consumption due to photosynthesis is significantly higher than the rate of CO₂ production from respiration.
- The video transcript indicates that the ratio of CO₂ consumption to CO₂ production during the daytime is approximately 10:1.

4. **Conclusion**:
- Therefore, during the daytime, green plants show a ratio of CO₂ consumption to CO₂ production of **10:1**.

### Final Answer:
The ratio of CO₂ consumption to CO₂ production in green plants during the daytime is **10:1**.
