Meristems are

Options

A. Mature cells
B. Well differentiated cells
C. Embryonal cells
D. None of these

Answer

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are specialized tissues in plants that are responsible for growth and development. They consist of undifferentiated cells that can divide continuously.

2. **Analyzing the Options**:
- The question provides four options:
- A) Mature cells
- B) Well differentiated cells
- C) Embryonal cells
- D) None of these

3. **Evaluating Option A - Mature Cells**:
- Mature cells are specialized cells that have completed their differentiation. Examples include sieve tubes and other specialized plant cells. Since meristematic cells are still dividing and not fully specialized, they cannot be classified as mature cells.

4. **Evaluating Option B - Well Differentiated Cells**:
- Well differentiated cells are those that have developed into specific types of cells with distinct functions. Meristematic cells are not well differentiated; they are primitive and retain the ability to divide and form various types of cells. Therefore, this option is also incorrect.

5. **Evaluating Option C - Embryonal Cells**:
- Embryonal cells are those that are involved in the early stages of development. Meristems can be considered embryonal because they are involved in the initial growth of the plant from the seed stage, where the plumule (shoot) and radical (root) develop. This makes option C a valid choice.

6. **Evaluating Option D - None of These**:
- Since we have identified that meristems can be classified as embryonal cells, this option is not correct.

7. **Conclusion**:
- Based on the analysis, the correct answer is **C) Embryonal cells**.
