Plants are known as purifier of air due to the process of

Options

A. respiration
B. photosynthesis
C. transpiration
D. desiccation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why plants are considered purifiers of air. We need to identify the process that contributes to this purification.

2. **Identifying the Processes**: The options given are respiration, photosynthesis, transpiration, and desiccation. We need to analyze each process:
- **Respiration**: This process involves the intake of oxygen and the release of carbon dioxide. It does not purify the air.
- **Photosynthesis**: This is the process where plants use carbon dioxide, water, and sunlight to produce glucose and oxygen. The oxygen produced is released into the atmosphere, which purifies the air.
- **Transpiration**: This is the process of water loss from plants. While it plays a role in water cycling, it does not directly purify the air.
- **Desiccation**: This refers to the drying out of plants and does not relate to air purification.

3. **Focusing on Photosynthesis**: Among the processes listed, photosynthesis is the key process that allows plants to take in carbon dioxide and release oxygen. This exchange is crucial for maintaining air quality.

4. **Conclusion**: Since photosynthesis reduces the amount of carbon dioxide in the atmosphere and produces oxygen, it is the process that makes plants natural air purifiers.

5. **Final Answer**: Plants are known as purifiers of air due to the process of **photosynthesis**.
