The term used for permanent cells that have reobtain meristematic property to perform cell division is

Options

A. Differentation
B. Dedifferentiation
C. Redifferentiation
D. determination

Answer

To solve the question regarding the term used for permanent cells that have regained meristematic properties to perform cell division, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Permanent Cells**:
- Permanent cells are those that have differentiated and lost the ability to divide. They perform specific functions in the plant body.

**Hint**: Remember that permanent cells are specialized and typically do not divide.

2. **Concept of Meristematic Cells**:
- Meristematic cells are undifferentiated cells that have the ability to divide and give rise to various types of cells. They are found in regions of growth in plants.

**Hint**: Think about where growth occurs in plants and the type of cells involved.

3. **Differentiation and De-differentiation**:
- Differentiation is the process where meristematic cells become specialized permanent cells and lose their ability to divide.
- De-differentiation is the process where these specialized cells regain the ability to divide again, essentially reverting to a meristematic state.

**Hint**: Focus on the prefix "de-" which indicates a reversal in the process.

4. **Re-differentiation and Determination**:
- Re-differentiation refers to the process where de-differentiated cells become specialized again.
- Determination is the process where a cell commits to becoming a specific type of cell or tissue in the future.

**Hint**: Consider the sequence of changes cells undergo from being undifferentiated to differentiated and back.

5. **Conclusion**:
- The term that describes permanent cells that have regained their ability to divide is **de-differentiation**.

**Final Answer**: The correct term is **de-differentiation**.
