Bryophyllum are reproduced by the formation of leaf buds on the margin of a leaf. while potatoes are reproduced by the bulbs of other potatoes. 

Answer 2

When a new plant grows from some part (root, leaves, stem) of parent plant ,it is known as vegetative propagation.

Advantages of vegetative propagation:

1. It can bear flowers, fruits earlier than seeds

2. It can help fruits and flowers who don’t have seeds to reproduce.

Banana and rose are raised by this method.

Bryophyllum reproduces through leaves and potatoes through the roots.
