Axillary and terminal buds develop by activity of -

Options

A. Lateral meristem.
B. Intercalary meristem
C. Apical meristem
D. Parenchyma

Answer

### Step-by-Step Solution:

1. **Understanding Buds**:
- Axillary buds are located at the base of leaves, while terminal buds are found at the tips of stems.

2. **Identifying Meristems**:
- There are different types of meristems in plants: apical meristem, lateral meristem, and intercalary meristem. Each has a specific role in plant growth.

3. **Role of Apical Meristem**:
- The apical meristem is responsible for the primary growth of plants, which includes the formation of terminal and axillary buds. It is located at the tips of roots and shoots.

4. **Exclusion of Other Meristems**:
- Lateral meristem contributes to secondary growth (thickening of stems and roots) but does not form axillary or terminal buds.
- Intercalary meristem is found at the base of internodes in monocots and is involved in regrowth, but it does not form terminal or axillary buds either.

5. **Conclusion**:
- Therefore, axillary and terminal buds develop primarily due to the activity of the **apical meristem**.

### Final Answer:
Axillary and terminal buds develop by the activity of **apical meristem**.
