Axillary bud and terminal bud are derived from the activity of

Options

A. lateral meristem
B. apical meristem
C. intercalary meristem
D. parenchyma

Answer

To answer the question regarding the origin of axillary buds and terminal buds, we will analyze the types of meristems and their functions in plant growth.

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are regions of undifferentiated cells in plants that are capable of division and growth. They are responsible for the growth of the plant.

2. **Types of Meristems**:
- There are three main types of meristems:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for primary growth (increasing height).
- **Intercalary Meristem**: Found at the nodes of the plant, it helps in the elongation of internodes.
- **Lateral Meristem**: Located in the vascular and cork cambium, responsible for secondary growth (increasing girth).

3. **Identifying the Correct Meristem**:
- The question specifically asks about axillary buds and terminal buds.
- **Axillary Buds**: These are located at the axils of leaves and can develop into branches or flowers.
- **Terminal Buds**: These are located at the tip of the stem and are responsible for the growth in height of the plant.

4. **Role of Apical Meristem**:
- The apical meristem is responsible for the formation of both axillary and terminal buds.
- As the apical meristem divides, it gives rise to new cells that differentiate into various structures, including buds.

5. **Conclusion**:
- Therefore, axillary buds and terminal buds are derived from the activity of the **apical meristem**.

### Final Answer:
Axillary bud and terminal bud are derived from the activity of **apical meristem**.
