Quiescent centre is present in

Options

A. Root tip
B. Stem tip
C. Flower
D. Leaf

Answer

**Step-by-Step Solution:**

1. **Understanding the Quiescent Center**: The quiescent center is a specific region in plant tissues where cell division occurs at a very low frequency. It plays a crucial role in maintaining the meristematic activity of the plant.

2. **Identifying Locations of Quiescent Centers**: The question provides four options: root tip, stem tip, flower, and leaf. We need to determine where the quiescent center is present among these options.

3. **Analyzing the Root Tip**: The root tip is known to contain the root apical meristem, which is responsible for the growth of roots. Within this region, the quiescent center is located, serving as a reserve of cells that can divide when needed.

4. **Examining Other Options**:
- **Stem Tip**: The shoot apex (or stem tip) contains apical meristem but does not have a quiescent center.
- **Flower**: The flower is a specialized structure derived from the shoot apical meristem and does not contain a quiescent center.
- **Leaf**: The leaf tip is a permanent structure derived from the shoot apical meristem and also does not have a quiescent center.

5. **Conclusion**: Since the quiescent center is specifically present in the root tip and not in the other options, the correct answer is the root tip.

**Final Answer**: The quiescent center is present in the root tip.
