Answer

To determine which statement is wrong for Cycas, we need to analyze each of the provided statements regarding its characteristics:

1. **Xylem have vessels**: This statement is incorrect. Cycas, being a gymnosperm, does not have vessels in its xylem. Instead, it has tracheids, which are the primary water-conducting cells in gymnosperms.

2. **Male cones are well developed**: This statement is correct. Cycas produces well-developed male cones that are essential for reproduction.

3. **It has coralloid roots**: This statement is also correct. Cycas has coralloid roots that are associated with nitrogen-fixing cyanobacteria, which help in nutrient absorption.

4. **Circinate leaves**: This statement is correct as well. Circinate vernation refers to the coiled arrangement of young leaves, which is a characteristic feature of Cycas.

Based on the analysis, the statement that is wrong for Cycas is: **"Xylem have vessels."**
