Quiescent centre in root meristem serves as

Options

A. site for storage of food which is utilized during maturation
B. reservoir of growth hormones
C. reserve for replensishmen of damaged cells of the meristem
D. region for absorption of water

Answer

### Step-by-Step Solution:

1. **Understanding the Quiescent Centre**:
- The quiescent centre is a specific region located in the root meristem. It was first described by Claus in 1956.

2. **Characteristics of the Quiescent Centre**:
- This centre is characterized by having low levels of DNA, RNA, and proteins, which indicates that the cells in this area are not actively dividing under normal conditions.

3. **Function of the Quiescent Centre**:
- The primary function of the quiescent centre is to serve as a reservoir of cells that can be activated to divide when the root cells are injured. This means that it plays a crucial role in the repair and replenishment of damaged cells in the root meristem.

4. **Distinguishing Functions**:
- It is important to note that the quiescent centre does not function as a food storage site, a reservoir for growth hormones, or a region for water absorption. Its main role is specifically related to the replenishment of damaged cells.

5. **Conclusion**:
- Therefore, the quiescent centre serves as a reserve for the replenishment of damaged cells in the root meristem, making it essential for the maintenance and repair of root tissues.

### Final Answer:
The quiescent centre in the root meristem serves as a reservoir for the replenishment of damaged cells.
