CAM helps the plants in

Options

A. Conserving water
B. Secondary growth
C. Disease resistance
D. Reproduction

Answer

**Step-by-Step Solution:**

1. **Understanding CAM**: CAM stands for Crassulacean Acid Metabolism. It is a photosynthetic adaptation found in some plants, particularly those in arid (dry) environments.

2. **Purpose of CAM**: The primary purpose of CAM is to help plants conserve water. This is crucial for survival in environments where water is scarce.

3. **Stomatal Behavior**: In CAM plants, the stomata (tiny openings on the leaves) remain closed during the day and open at night. This unique behavior helps to minimize water loss during the hotter daytime hours.

4. **Gas Exchange**: By opening the stomata at night, CAM plants can take in carbon dioxide (CO2) without losing much water. The CO2 is then converted into organic acids (like malate) and stored.

5. **Photosynthesis Process**: During the day, when the stomata are closed, the stored organic acids are used in the photosynthesis process. The plant can still produce sugars without losing water.

6. **Conclusion**: Therefore, CAM helps plants primarily in conserving water, which is essential for their survival in arid conditions.
