Select the odd one out w.r.t. adventitious bud?

Options

A. Foliar bud
B. Cauline bud
C. Extra axilary bud
D. Radical bud

Answer

To solve the question "Select the odd one out with respect to adventitious bud," we need to analyze the options provided in the context of adventitious buds and their characteristics.

### Step-by-Step Solution:

1. **Understand Adventitious Buds**:
- Adventitious buds are those that form in unusual places on a plant, not in the typical locations like the tips of stems or the axils of leaves. They can arise from roots, stems, or leaves.

2. **Identify the Options**:
- Based on the video transcript, the options mentioned are:
- A) Foliar
- B) Cauline
- C) Extra Axillary
- D) Radical

3. **Analyze Each Option**:
- **Foliar Buds**: These are buds that develop on leaves (e.g., Bryophyllum). They are considered adventitious because they form in an unusual location (the leaf).
- **Cauline Buds**: These are buds that develop on the stem. They are also considered adventitious if they appear in unexpected places on the stem.
- **Extra Axillary Buds**: These buds form in the axil of the leaf, which is a typical location for bud formation. Therefore, they do not qualify as adventitious.
- **Radical Buds**: These are buds that develop from the root. They are considered adventitious since they arise from an unusual location (the root).

4. **Determine the Odd One Out**:
- Among the options, **Extra Axillary Buds (C)** is the only type that forms in a typical location (the axil of the leaf) and does not qualify as adventitious. The other options (Foliar, Cauline, and Radical) involve buds forming in unusual locations.

5. **Conclusion**:
- The odd one out with respect to adventitious buds is **C) Extra Axillary**.
