Production of cork cambium is an example for

Options

A. differentiation
B. redifferentiation
C. dedifferentiation
D. degeneration

Answer

**Step-by-Step Solution:**

1. **Understanding Cork Cambium**: Cork cambium, also known as felogen, is a type of lateral meristematic tissue found in plants. It plays a crucial role in the formation of the outer protective layer of the plant, particularly in woody plants.

2. **Production of Cork Cambium**: The cork cambium is produced from the outer part of the cortex through a specific process. As the plant stem increases in girth, the outer layers (epidermis and cortex) need to be replaced by new meristematic tissue to accommodate this growth.

3. **Identifying the Process**: The process by which the outer cortex cells revert to a meristematic state (capable of division) to form cork cambium is known as de-differentiation. This is distinct from differentiation, where cells become specialized and lose their ability to divide.

4. **Eliminating Other Options**:
- **Differentiation**: This is the process where unspecialized cells become specialized, which does not apply to the formation of cork cambium.
- **Re-differentiation**: This refers to the maturation of previously de-differentiated cells back into specialized cells, which is not the case here.
- **Degeneration**: This involves the decline in tissue function and structure, which is not relevant to the formation of cork cambium.

5. **Conclusion**: Therefore, the production of cork cambium is an example of de-differentiation.

**Final Answer**: The production of cork cambium is an example of option 3: de-differentiation.
