Which of the following statement is incorrect for gymnosperm?

Options

A. Leaves are always compound
B. In Cycas, the pinnate leaves persist for a many years
C. Thick cuticle and sunken stomata of needle-like leaves also help to reduce water loss
D. In conifers, the needle-like leaves reduce the surface area

Answer

To determine which statement is incorrect for gymnosperms, we will analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Understanding Gymnosperms**:
- Gymnosperms are a group of seed-producing plants that do not form flowers or fruits. Their seeds are exposed or naked, meaning they are not enclosed in an ovary wall.

2. **Analyzing the Statements**:
- We need to evaluate each statement given in the question regarding gymnosperms.

3. **Statement Evaluation**:
- **Statement 1**: "Leaves are always compound."
- This statement is incorrect. Gymnosperms can have both simple and compound leaves. For example, the leaves of conifers (like pines) are needle-like and simple, while cycads have compound leaves.

- **Statement 2**: "In Cycas, the pinnate leaves persist for many years."
- This statement is correct. Cycas, a type of cycad, has pinnate leaves that can last for several years.

- **Statement 3**: "Thick cuticle, sunken stomata of needle-like leaves also help to reduce water loss."
- This statement is correct. The adaptations in gymnosperms, such as a thick cuticle and sunken stomata, help minimize water loss, especially in arid environments.

- **Statement 4**: "In conifers, the needle-like leaves reduce the surface area."
- This statement is correct. Needle-like leaves have a reduced surface area which helps in reducing water loss.

4. **Conclusion**:
- The only incorrect statement regarding gymnosperms is "Leaves are always compound." Therefore, this is the answer to the question.

### Final Answer:
The incorrect statement for gymnosperms is: **"Leaves are always compound."**
