The correct Answer is:
To solve the question regarding the correctness of the given statements about Crassulacean acid metabolism and stomata in succulent plants, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Statement 1**: - The first statement claims that "Crassulacean acid metabolism (CAM) occurs in succulent plants which grow in xeric conditions." - CAM is a photosynthetic adaptation found in many succulent plants that allows them to conserve water. In xeric (dry) conditions, these plants open their stomata at night to take in carbon dioxide, which helps minimize water loss during the hotter daytime hours. 2. **Understanding Statement 2**: - The second statement states that "Stomata are generally sunken in succulent plants." - Sunken stomata are a common adaptation in succulent plants. This feature helps reduce water loss by creating a microenvironment that retains moisture around the stomata, further minimizing transpiration. 3. **Evaluating the Statements**: - Both statements are accurate. CAM is indeed a mechanism used by succulent plants in dry environments, and sunken stomata are a structural adaptation that helps these plants conserve water. 4. **Conclusion**: - Since both statements are correct, the correct option is that both statements are true. ### Final Answer: Both Statement 1 and Statement 2 are correct.
