Quiescent centre is found in

Options

A. (a) Stem
B. (b) Root
C. (c) Leaves
D. (d) None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Quiescent Center**: The quiescent center is a specific region in plants where cells are in a dormant state and do not actively divide.

2. **Location of Quiescent Center**: This center is primarily found in the root tips of plants, specifically just above the root cap.

3. **Function of Quiescent Center**: The cells in the quiescent center are preserved for times of need, such as during injury or damage to the tissue. They can become active and divide when necessary.

4. **Historical Context**: The quiescent center was identified by scientist Clovis in 1958, specifically in the plant species Zea mays (commonly known as maize).

5. **Characteristics of Quiescent Center**: Observations made about the quiescent center include:
- Presence of few mitochondria and endoplasmic reticulum.
- A very small nucleus.
- No cell division or DNA synthesis occurring in this region.

6. **Conclusion**: Based on the above points, the quiescent center is found in the root tips of plants. Therefore, the correct answer to the question is that the quiescent center is found in the roots.

**Final Answer**: The quiescent center is found in the roots.
