Quiescent cells in the root tip cells are in which phase of cell cycle of mitosis ?

Options

A. `G_(1)`
B. `G_(0)`
C. `G_(2)`
D. M

Answer

To answer the question about the phase of the cell cycle in which quiescent cells in the root tip are found, let's break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**:
- The cell cycle consists of two main phases: Interphase and M phase (mitotic phase).
- Interphase is further divided into three sub-phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

2. **Defining Quiescent Cells**:
- Quiescent cells are those that are in a state of inactivity and do not actively divide. They are often referred to as being in the G0 phase.

3. **Identifying the G0 Phase**:
- The G0 phase is a resting state where cells are metabolically active but not actively preparing to divide. Cells can enter this phase from G1 if they do not receive signals to proceed with division.

4. **Relating to Root Tip Cells**:
- In the context of root tip cells, which are often involved in growth and development, quiescent cells are those that are not currently dividing but are still capable of re-entering the cell cycle when needed.

5. **Conclusion**:
- Therefore, quiescent cells in the root tip are in the G0 phase of the cell cycle.

### Final Answer:
Quiescent cells in the root tip cells are in the G0 phase of the cell cycle.
