The correct Answer is:
To determine where centrifugal development of xylem occurs, we need to understand the concepts of xylem arrangement in plants. ### Step-by-Step Solution: 1. **Understanding Xylem Development**: Xylem can develop in two ways: centrifugal and centripetal. In centrifugal development, the xylem develops outward from the center, while in centripetal development, it develops inward towards the center. 2. **Identifying the Types of Xylem Arrangement**: - **Endarch Condition**: In this condition, the protoxylem (the first xylem to develop) is located towards the center, and the metaxylem (the later-developed xylem) is located towards the periphery. This arrangement is typical of stems. - **Exarch Condition**: In this condition, the protoxylem is located towards the outside, and the metaxylem is towards the center. This arrangement is typical of roots. 3. **Analyzing the Options**: The question asks about centrifugal development of xylem. Based on the definitions: - In stems, xylem develops in an endarch manner (centrifugal). - In roots, xylem develops in an exarch manner (centripetal). - Leaves and flowers do not primarily exhibit centrifugal development of xylem. 4. **Conclusion**: Based on the above analysis, the centrifugal development of xylem occurs in the stem. ### Final Answer: Centrifugal development of xylem occurs in the stem.
