Ans.This method of propagation is also called micro-propagation since it uses only a small part of plant.
Cloning
It is the latest method of vegetative propagation. In this method, identical offsprings are produced from a single parent using its vegetative tissue or cell. Tissue culture is the technique applied in this method.
Tissue Culture
Tissues are taken from any part of plant and are put in a suitable nutrient medium. The tissue cells start mitosis and produce masses of cells called calluses are transferred to other medium that contains different hormones for the formation of roots, stem and leaves. Calluses make these structures and grow into new small plants. The small plants are then planted in pots and then in fields.
