Question

why is vegetative reproduction is practised

Answer 1

There are many plants in which parts like the root, stem and leaves develop into new plants under appropriate conditions. Hence in such plants, vegetative propagation can be used for reproducing the entire plant. Plants raised by vegetative propagation can bear flowers and fruits earlier than those produced from seeds. Such methods also make possible the propagation of plants such as banana, orange, rose etc. that have lost the capacity to produce seeds. Another advantage is that all plants produced are genetically similar enough to the parent plant.
