Centripetal development of xylem is present in

Options

A. Dicot root
B. Dicot stem
C. Monocot stem
D. Branches of stem

Answer

To answer the question about where centripetal development of xylem is present, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Centripetal Development**:
- Centripetal development refers to the arrangement of xylem where the outermost xylem is smaller than the innermost xylem. This means that as you move from the outside towards the center of the plant structure, the xylem cells increase in size.

2. **Identify the Structure Involved**:
- In plants, xylem is responsible for the transport of water and nutrients. The arrangement of xylem can vary in different types of plant structures, particularly in roots and stems.

3. **Differentiate Between Plant Types**:
- There are two main types of flowering plants: dicots and monocots. Understanding the differences in their vascular arrangements is crucial.

4. **Focus on Dicot Roots**:
- In dicot roots, the xylem exhibits a centripetal pattern of development. This is characterized by the outer xylem being smaller than the inner xylem, which aligns with the definition of centripetal development.

5. **Conclude the Answer**:
- Based on the understanding that centripetal development of xylem is specifically observed in dicot roots, we can conclude that the correct answer to the question is "dicot root".

### Final Answer:
Centripetal development of xylem is present in **dicot root**.
