Stomata help in …………..

Options

A. respiration
B. photosynthesis
C. transpiration
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Stomata**: Stomata are small openings found on the surface of leaves and stems of plants. They play a crucial role in gas exchange.

2. **Function in Respiration**: Stomata allow plants to take in oxygen (O2) and release carbon dioxide (CO2) during respiration. This process is essential for energy production in plants.

3. **Role in Photosynthesis**: During photosynthesis, stomata facilitate the intake of carbon dioxide (CO2) from the atmosphere, which is used to produce glucose and oxygen. The oxygen produced is then released back into the atmosphere through the stomata.

4. **Involvement in Transpiration**: Stomata also play a vital role in transpiration, which is the process of water vapor loss from the plant to the atmosphere. This helps in regulating water loss and maintaining temperature within the plant.

5. **Conclusion**: Since stomata are involved in respiration, photosynthesis, and transpiration, the correct answer to the question "Stomata help in ………….." is that they help in all of these processes.

**Final Answer**: Stomata help in respiration, photosynthesis, and transpiration (Option D: all of these).
