The cells of the quiescent centre are characterised by

Options

A. having dense cytoplasm and prominent nuclei
B. having light cytoplasm and small nuclei
C. dividinig regularly to add to the corpus
D. dividing regularly to add to tunica.

Explanation

### Step-by-Step Solution:

1. **Understanding the Quiescent Centre (QCN)**:
- The Quiescent Centre is located at the center of the root apex. It plays a crucial role in the growth and development of roots.

2. **Function of the Quiescent Centre**:
- The primary function of the QCN is to replace the meristematic cells in the root cap. This means that it helps in maintaining the population of cells that are essential for root growth.

3. **Characteristics of the Cells in the Quiescent Centre**:
- **Light Cytoplasm**: The cells in the QCN have a light or less dense cytoplasm compared to other cells. This characteristic is important as it indicates a lower level of metabolic activity.
- **Many Small Nuclei**: The cells also contain many small nuclei. This feature is significant as it reflects the quiescent nature of these cells, which are not actively dividing but are still vital for the root's functionality.

4. **Conclusion**:
- Therefore, the cells of the Quiescent Centre are characterized by having light cytoplasm and many small nuclei.

### Final Answer:
The cells of the Quiescent Centre are characterized by light cytoplasm and many small nuclei.
