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 re-obtained meristematic property to perform cell division, we can follow these steps:

### Step 1: Understand the Terms
- **Permanent Cells**: These are cells that have differentiated and typically do not divide.
- **Meristematic Cells**: These are undifferentiated cells that have the ability to divide and form new cells.

### Step 2: Identify the Process
- The question asks for a term that describes permanent cells that regain the ability to divide. This implies that these cells have lost their ability to divide (differentiated) but can revert back to a state where they can divide again.

### Step 3: Analyze the Options
1. **Differentiation**: This refers to the process where meristematic cells divide and specialize into permanent cells. This is not the correct term for cells regaining division capability.

2. **De-differentiation**: This term describes the process where differentiated cells revert back to a meristematic state, regaining their ability to divide. This matches the requirement of the question.

3. **Re-differentiation**: This refers to differentiated cells that change back to a different specialized state. This does not imply regaining division capability.

4. **Determination**: This is the process by which a cell becomes committed to a specific fate or function. It does not relate to regaining the ability to divide.

### Step 4: Conclusion
Based on the analysis, the correct term for permanent cells that have re-obtained meristematic property to perform cell division is **De-differentiation**.

### Final Answer
**De-differentiation**
