Give scientific reasons for the following statements:
The number of bryophyllum keep on increasing in garden.

Explanation

In some plants, parts like root, stem and leaves can give rise to buds in dormant state which acts as reproductive unit.
`rarr` When suitable moisture and temperature are provided to these dormant structures, they form new plants.
`rarr` Buds found on the leaves of bryophyllum induce vegetative propagation.
`rarr` In garden, the detatched buds germinate under favourable conditions such as moisture, nutrients, suitable temperature.
Hence, the number of bryophyllum keep on increasing in garden.
