Answer Key : (4) -

The plant tissue or organ excised and used for in vitro culture is known as explant.  Any plant part such as shoot tip, root tip, leaf tip, pollen grains, etc, may be used as an explant.  The choice of explant depends mainly on the objective of the culture and the regeneration potential of the different organs of a plant species.
