Quiescent zone is the zone of

Options

A. Less mitotic activity in the root apex
B. Less mitotic activity in the shoot apex
C. Maximum mitotic activity in the root apex
D. Maximum mitotic activity in the shoot apex

Answer

**Step-by-Step Solution:**

1. **Understanding the Quiescent Zone**: The quiescent zone is a specific area in the root and shoot apices of plants. It is characterized by a low level of cellular activity.

2. **Identifying the Characteristics**: The term "quiescent" refers to a state of rest or inactivity. In the context of plant biology, this means that the cells in the quiescent zone undergo less mitotic activity compared to other zones.

3. **Locating the Quiescent Zone**: The quiescent zone is primarily found in the root apex. It serves as a reserve meristem, which can become active when needed, such as during growth or repair.

4. **Differentiating Between Root and Shoot Apices**: The shoot apex has an apical meristem that is actively dividing, thus it does not have a quiescent zone. In contrast, the root apex contains the quiescent zone where mitotic activity is lower.

5. **Conclusion**: Based on the characteristics of the quiescent zone, the correct answer to the question is that the quiescent zone is the zone of less mitotic activity in the root apex.

**Final Answer**: The quiescent zone is the zone of less mitotic activity in the root apex.
