In which of the following, vegetative propagule is the'' leaf buds'' through which the plant can be vegetatively propagated

Options

A. Agave and Kalanchoe
B. Bryophyllum and Kalanchoe
C. Asparagus and Bryophyllum
D. Chrysanthemum and Agave

Explanation

To solve the question regarding which plant propagates vegetatively through leaf buds, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Vegetative Propagation**:
- Vegetative propagation is a form of asexual reproduction in plants where new individuals are produced from the vegetative parts of the plant such as roots, stems, and leaves.

2. **Identify the Vegetative Propagules**:
- The question specifically asks for plants that use "leaf buds" as their vegetative propagules.

3. **Examine the Given Options**:
- The options provided include:
- Agave
- Kalanchoe
- Bryophyllum
- Asparagus
- Chrysanthemum
- Mint

4. **Analyze Each Option**:
- **Agave**: Propagates through bulbils (fleshy buds), not leaf buds.
- **Kalanchoe**: Known for its ability to propagate through leaf buds. The leaves can produce adventitious buds.
- **Bryophyllum**: Similar to Kalanchoe, it propagates through leaf buds that develop on the margins of the leaves.
- **Asparagus**: Propagates through roots, not leaf buds.
- **Chrysanthemum and Mint**: These plants propagate through suckers, which are underground branches.

5. **Determine the Correct Answer**:
- Both Kalanchoe and Bryophyllum utilize leaf buds for vegetative propagation. Therefore, the correct answer is that both Kalanchoe and Bryophyllum are the plants that can be vegetatively propagated through leaf buds.

### Final Answer:
The correct answer is **Kalanchoe and Bryophyllum**.
