Bryophyllum is the best example of propagation by...............

Answer

**Step-by-Step Solution:**

1. **Understanding Bryophyllum**: Bryophyllum is a type of plant known for its unique method of reproduction. It is often referred to as an "air plant."

2. **Type of Reproduction**: Bryophyllum primarily reproduces asexually. Asexual reproduction does not involve the fusion of gametes, which distinguishes it from sexual reproduction.

3. **Vegetative Propagation**: The method of asexual reproduction in Bryophyllum is specifically known as vegetative propagation. This means that new plants can grow from parts of the parent plant without the need for seeds.

4. **Role of Leaves**: In Bryophyllum, vegetative propagation occurs through its leaves. The leaves are broad and have notches along their margins.

5. **Formation of Adventitious Buds**: From these notches on the leaves, structures called epiphyllous buds arise. These buds have the potential to develop into new plants.

6. **Development of New Plants**: The epiphyllous buds can grow shoots, small leaves, and adventitious roots. Once these new plants detach from the parent leaf and come into contact with the soil, they can grow into mature plants.

7. **Conclusion**: Therefore, Bryophyllum is best known for propagation by vegetative means, specifically through its leaves.

**Final Answer**: Bryophyllum is the best example of propagation by vegetative propagation.
