What is common in Bryophyllum and Allium?

Options

A. Both are members of family liliaceae
B. Both reproduce only sexually
C. Both reproduce vegetatively
D. Both lack heterospory

Answer

To answer the question "What is common in Bryophyllum and Allium?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**:
- Bryophyllum is a genus of plants known for its ability to reproduce vegetatively through leaf buds.
- Allium is a genus that includes onions and garlic, which are also capable of vegetative reproduction.

2. **Understand Reproductive Methods**:
- Bryophyllum reproduces asexually through vegetative reproduction. This occurs when new plants grow from the buds located on the leaf margins.
- Allium also reproduces vegetatively, primarily through bulbs, which are underground storage organs that can produce new plants.

3. **Examine the Families**:
- Bryophyllum belongs to the family Crassulaceae.
- Allium belongs to the family Amaryllidaceae.
- Since they belong to different families, this is not a common characteristic.

4. **Evaluate Heterospory**:
- Heterospory refers to the production of two different types of spores (microspores and megaspores).
- Both Bryophyllum and Allium are angiosperms, and Allium does exhibit heterospory. However, Bryophyllum does not, making this option incorrect for commonality.

5. **Conclusion**:
- The commonality between Bryophyllum and Allium is that **both reproduce vegetatively**. This is the key similarity between the two genera.

### Final Answer:
Both Bryophyllum and Allium reproduce vegetatively.
