Cells that usually do not divide but may gain the ability to divide at specific growth stage of plant is

Options

A. Meristematic
B. Differentiated cell
C. Dedifferentiated cell
D. Redifferentiated cell

Answer

To solve the question regarding the type of cells in plants that usually do not divide but may gain the ability to divide at specific growth stages, we will analyze the different types of plant cells mentioned in the video transcript.

### Step-by-Step Solution:

1. **Understanding Cell Types**:
- **Meristematic Cells**: These are actively dividing cells found in the meristematic regions of plants (like the tips of roots and shoots). They continuously divide to form new tissues.
- **Differentiated Cells**: These cells have already specialized into specific types (like stems, leaves, etc.) and typically do not divide. Their fate is predetermined.
- **De-differentiated Cells**: These cells were once differentiated but can revert to a simpler form and regain the ability to divide under certain conditions.
- **Re-differentiated Cells**: These cells stop dividing and adapt to a mature form, but they do not regain the ability to divide.

2. **Identifying the Correct Cell Type**:
- The question specifically asks for cells that usually do not divide but may gain the ability to divide at a specific growth stage.
- Among the options, **de-differentiated cells** fit this description as they can revert from a specialized state to a simpler state and regain division capability.

3. **Conclusion**:
- Therefore, the correct answer to the question is **de-differentiated cells**.

### Final Answer:
The cells that usually do not divide but may gain the ability to divide at specific growth stages of a plant are **de-differentiated cells**.
