Adaptations to plants against dry environmental conditions is `//` are

Options

A. Stomata arranged in deep pits
B. Stomata remain open during day time
C. CAM pathway
D. More than one option is correct

Answer

To solve the question regarding adaptations of plants to dry environmental conditions, we will analyze each option provided and determine which adaptations are indeed correct.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the adaptations of plants that help them survive in dry environments. These adaptations are crucial for minimizing water loss and maximizing water retention.

2. **Analyzing Option 1**: "Stomata arranged in deep pits."
- **Explanation**: In arid conditions, many plants have stomata that are located in deep pits or grooves. This adaptation helps to reduce water loss by minimizing exposure to the air and sunlight, which can cause evaporation.
- **Conclusion**: This statement is **correct**.

3. **Analyzing Option 2**: "Stomata remain open during daytime."
- **Explanation**: In dry environments, plants typically do not keep their stomata open during the day. Instead, they often close their stomata during the hottest parts of the day to conserve water. Some plants may open their stomata at night (as seen in CAM plants) to reduce water loss.
- **Conclusion**: This statement is **incorrect**.

4. **Analyzing Option 3**: "CAM pathway."
- **Explanation**: The Crassulacean Acid Metabolism (CAM) pathway is an adaptation found in some plants that allows them to fix carbon dioxide at night when temperatures are cooler and humidity is higher. This reduces water loss since the stomata are closed during the day. This adaptation is particularly beneficial for plants in arid environments.
- **Conclusion**: This statement is **correct**.

5. **Final Evaluation**: Now that we have analyzed all the options:
- Option 1 is correct.
- Option 2 is incorrect.
- Option 3 is correct.
- Therefore, the correct answer to the question is that more than one option is correct.

### Final Answer:
The correct adaptations of plants against dry environmental conditions are:
- Stomata arranged in deep pits (correct)
- CAM pathway (correct)

Thus, the answer is that **more than one option is correct**.
