Which one of the following is not formed from procambium?

Options

A. Xylem
B. Phloem
C. Intrafascicular cambium
D. Interfascicular cambium

Answer

To solve the question "Which one of the following is not formed from procambium?", we need to analyze the options provided and understand the role of procambium in plant anatomy.

### Step-by-Step Solution:

1. **Understanding Procambium**:
- Procambium is a type of meristematic tissue in plants. It is responsible for the formation of primary vascular tissues.

2. **Identifying Products of Procambium**:
- Procambium gives rise to:
- **Primary Xylem**: The tissue responsible for water conduction.
- **Primary Phloem**: The tissue responsible for food conduction.
- Therefore, options related to xylem and phloem can be eliminated as they are formed from procambium.

3. **Analyzing the Remaining Options**:
- The remaining options are:
- **Intrafascicular Cambium**: This is the cambium located between the primary xylem and primary phloem. Since it is derived from procambium, this option can also be eliminated.
- **Interfascicular Cambium**: This cambium is formed from the medullary rays that lie between vascular bundles and is not derived from procambium.

4. **Conclusion**:
- Since the interfascicular cambium is not formed from procambium, it is the correct answer to the question.

### Final Answer:
- **Interfascicular Cambium** is not formed from procambium.
