D. Meristematic tissue

Answer

To answer the question, "The cells or tissues of plants which have lost the power of division are called," we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand the Question
The question is asking for the name of plant cells or tissues that can no longer divide.

### Step 2: Analyze the Options
1. **Meristematic Tissue**:
- These tissues consist of actively dividing cells. Therefore, they do not fit the criteria of having lost the power of division.
- **Conclusion**: Incorrect option.

2. **Protoderm Tissue**:
- This is a type of meristematic tissue that gives rise to the epidermis of the plant. Since it is a meristematic tissue, it also continues to divide.
- **Conclusion**: Incorrect option.

3. **Promagistem**:
- This refers to a portion of the primary meristem. Like the previous options, it is also involved in division and growth.
- **Conclusion**: Incorrect option.

4. **Permanent Tissue**:
- Permanent tissues are formed when meristematic tissues lose their ability to divide. These tissues are differentiated and perform specific functions in the plant.
- **Conclusion**: Correct option.

### Step 3: Final Answer
Based on the analysis, the correct answer is **Permanent Tissue**.
