Xylem produced through centifugal differentiation is

Options

A. Exarch
B. Endarch
C. Measarch
D. Centrarch

Answer

To answer the question "Xylem produced through centrifugal differentiation is:", we will analyze the given options and determine which one correctly describes the process of centrifugal differentiation in xylem development.

### Step-by-Step Solution:

1. **Understanding Centrifugal Differentiation**:
- Centrifugal differentiation refers to the process where xylem develops outward from the center of the stem towards the periphery. This means that the newer xylem cells are formed on the outside, pushing older cells inward.

2. **Analyzing the Options**:
- **Option A: Exerge**: This refers to xylem that develops inward, which is known as centripetal differentiation. Therefore, this option is incorrect.
- **Option B: Enderge**: This option describes xylem that develops in multiple strands, with each strand growing outward towards the periphery of the stem. This is consistent with centrifugal differentiation, making this option correct.
- **Option C: Massage**: In this condition, xylem develops from the middle towards both the center and the periphery. This is not centrifugal differentiation, so this option is incorrect.
- **Option D: Centrate**: This describes a condition where xylem forms a chamber in the middle of the stem, surrounded by metaxylem and protoxylem. This does not represent centrifugal differentiation, making this option incorrect.

3. **Conclusion**:
- Based on the analysis, the correct answer is **Option B: Enderge**, as it accurately describes xylem produced through centrifugal differentiation.

### Final Answer:
**Xylem produced through centrifugal differentiation is: Enderge.**
