Options

A. leaf
B. root
C. dicot stem
D. monocot stem

Answer

**Step-by-Step Solution:**

1. **Understanding Centripetal Xylem:**
- The term "centripetal xylem" refers to the growth pattern of xylem tissue in plants. Specifically, it indicates that the xylem develops from the outer layers of the plant tissue towards the inner layers.

2. **Identifying Where Centripetal Xylem Occurs:**
- This type of growth is characteristic of roots. In roots, the xylem is formed from the outer side and moves inward, which is the definition of centripetal growth.

3. **Contrasting with Other Plant Parts:**
- In contrast, in shoots (stems), the xylem develops in a centrifugal manner, meaning it grows from the inner part of the plant outward. This is important to note as it differentiates the growth patterns in roots and shoots.

4. **Conclusion:**
- Based on the definitions and characteristics discussed, centripetal xylem is specifically a feature of roots. Therefore, the correct answer to the question is option B: root.

**Final Answer:**
Centripetal xylem is the characteristic of **roots** (Option B).
