Explanation
Identical offsprings are produced from a single parent using its vegetative tissue or cell.
Micro-Propagation
This method of propagation is also called micro-propagation since it uses only a small part of plant.
(2) Tissue Culture
Introduction
It is the technique applied in cloning.
Explanation
(i) Tissues are taken from any part of plant and are put in a suitable nutrient medium.
(ii) The tissue cells start mitosis and produce masses of cells called calluses which are transferred to other medium containing different hormones.
