D. (d) motile sperms

Answer

To determine which statement about Cycas is incorrect, we will analyze each option provided step by step.

### Step-by-Step Solution:

1. **Understanding Cycas**:
- Cycas is a genus of plants commonly known as sago palms and belongs to the group of gymnosperms. Gymnosperms are characterized by their seed-producing capabilities without the formation of flowers.

2. **Evaluating Option A**:
- The statement claims that "xylem has vessels."
- In gymnosperms, including Cycas, the xylem does not contain vessels; instead, it consists primarily of tracheids. Therefore, this statement is **incorrect**.

3. **Evaluating Option B**:
- The statement says that "leaves show circinate vernation."
- This is a true statement. Cycas leaves are indeed compound and exhibit circinate vernation, where the leaves unfurl in a coiled manner.

4. **Evaluating Option C**:
- The statement claims that "it does not have organized female flowers."
- This is also true. Cycas does not produce flowers as it is a gymnosperm; instead, it has cones for reproduction.

5. **Evaluating Option D**:
- The statement says that "Cycas has motile sperm."
- This is true as well. Cycas is known for having motile sperm that can swim to the egg for fertilization.

6. **Conclusion**:
- After evaluating all the options, the only incorrect statement about Cycas is Option A, which states that "xylem has vessels."

### Final Answer:
The incorrect statement about Cycas is: **A. Xylem has vessels.**
