Which of the following statements about quiescent center is incorrect?

Options

A. Low mitochondrial activity
B. Slowly dividing cell
C. Present in central part of root apex
D. High protein and DNA content

Answer

To determine which statement about the quiescent center is incorrect, we need to analyze each option provided regarding the characteristics of the quiescent center (also known as the G0 phase).

### Step-by-Step Solution:

1. **Understanding the Quiescent Center**:
- The quiescent center is a region in plant roots that contains cells in a resting state. These cells are metabolically active but do not divide or grow.

2. **Evaluating Each Statement**:
- **Statement 1**: "Low mitochondrial activity."
- This statement is correct. In the quiescent center, cells have low metabolic activity, which includes low mitochondrial activity.

- **Statement 2**: "Slowly dividing cells."
- This statement is also correct. Cells in the quiescent center are not actively dividing; they are in a resting phase.

- **Statement 3**: "Present in the central part of the root apex."
- This statement is correct as well. The quiescent center is located at the central part of the root apex, where it plays a role in maintaining the root meristem.

- **Statement 4**: "High protein and DNA content."
- This statement is incorrect. Cells in the quiescent center do not have high protein and DNA content as they are not actively dividing or undergoing mitosis. High protein and DNA content is typically associated with actively dividing cells.

3. **Conclusion**:
- The incorrect statement about the quiescent center is the fourth one: "High protein and DNA content."

### Final Answer:
The incorrect statement about the quiescent center is: **"High protein and DNA content."**
