The correct Answer is:
### Step-by-Step Solution: 1. **Understanding CAM**: CAM stands for Crassulacean Acid Metabolism. It is a unique photosynthetic pathway found in certain plants, particularly those in arid environments. 2. **Function of CAM**: The primary function of CAM is to enable plants to perform photosynthesis while minimizing water loss. This is crucial for survival in dry conditions. 3. **Mechanism of CAM**: CAM plants open their stomata at night to take in carbon dioxide (CO2) and store it as malic acid. During the day, the stomata close to reduce water loss, and the stored CO2 is used for photosynthesis. 4. **Water Conservation**: By using this method, CAM plants significantly reduce transpiration (loss of water through stomata), allowing them to conserve water effectively. 5. **Survival in Harsh Conditions**: This adaptation allows CAM plants to thrive in environments where water is scarce, such as deserts. 6. **Examples of CAM Plants**: Common examples of CAM plants include cacti, orchids, and sedums. These plants have evolved to optimize water usage. 7. **Conclusion**: Therefore, the correct answer to the question "CAM helps the plants in" is that it helps in conserving water. ### Answer: **Conserving Water** ---
