Axillary bud develop by activity of

Options

A. Lateral meristem
B. Shoot Apical meristem
C. Root Apical meristem
D. Intercalary meristem

Answer

**Step-by-Step Solution:**

1. **Understanding Axillary Buds**:
- Axillary buds are small buds that develop in the axil of a leaf, which is the angle between the leaf and the stem. They have the potential to develop into branches or flowers.

2. **Role of Meristems**:
- Meristems are regions in plants where cells remain undifferentiated and are capable of division, leading to growth. There are different types of meristems: apical meristems (found at the tips of roots and shoots), lateral meristems (responsible for thickness), and intercalary meristems (located at the base of leaves or internodes).

3. **Identifying the Correct Meristem for Axillary Bud Development**:
- The development of axillary buds is primarily influenced by the activity of the **axillary meristem**, which is associated with the apical meristem at the tip of the stem. This is where new growth occurs.

4. **Hormonal Influence**:
- Auxin, a plant hormone, plays a crucial role in the development of axillary buds. It promotes cell division and growth, allowing the axillary buds to develop into new branches or flowers.

5. **Eliminating Incorrect Options**:
- **Lateral Meristem**: This is involved in the thickening of stems and does not develop axillary buds.
- **Root Apical Meristem**: This is responsible for root growth and does not contribute to the development of axillary buds.
- **Intercalary Meristem**: This is involved in the growth of internodes and is not responsible for axillary bud formation.

6. **Conclusion**:
- The correct answer is that axillary buds develop primarily due to the activity of the **apical meristem** located at the upper part of the stem, influenced by the hormone auxin.

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