Choose odd one w.r.t vegetative propagule involved in cultivation in following plants

Options

A. Banana
B. Ginger
C. Bryophyllum
D. Potato

Answer

To solve the question of identifying the odd one out with respect to vegetative propagules involved in the cultivation of the given plants (banana, ginger, Bryophyllum, and potato), we can follow these steps:

### Step-by-Step Solution:

1. **Understand Vegetative Propagules**:
- Vegetative propagules are plant structures that can develop into new plants. They are involved in vegetative propagation, which is a type of asexual reproduction.

2. **Analyze Each Plant**:
- **Banana**: The vegetative propagule is a **rhizome**, which is an underground stem modification. It grows horizontally and produces new shoots from its buds.
- **Ginger**: Similar to banana, ginger also reproduces through a **rhizome**, which is again an underground stem modification.
- **Bryophyllum**: This plant reproduces through **adventitious leaf buds** that grow on the margins of its leaves. When these buds come into contact with the soil, they can develop into new plants.
- **Potato**: The vegetative propagule here is the **eye** of the potato, which is a node on the tuber (an underground stem modification). Each eye can sprout and grow into a new plant.

3. **Identify the Odd One Out**:
- Now, we compare the vegetative propagules:
- Banana: Rhizome (underground stem)
- Ginger: Rhizome (underground stem)
- Bryophyllum: Adventitious leaf buds (not a stem)
- Potato: Eye (node on an underground stem)
- The first three (banana, ginger, and potato) involve underground stem modifications (rhizomes or tubers), while Bryophyllum uses leaf buds for propagation.

4. **Conclusion**:
- The odd one out is **Bryophyllum**, as it does not utilize an underground stem modification for vegetative propagation.

### Final Answer:
**Bryophyllum** is the odd one out with respect to vegetative propagules involved in cultivation.
