. An unorganized mass of cells in plants is called as:-
(a) Callus
(b) Explant
(c) Meristem
(d) Axillary bud
Best Answer
(a) Callus is usually produced by culturing explants in tissue culture. Explant is any part of a plant that is cut and grown “in vitro”. Sometimes in woody plants a superficial tissue develops in response to wounding which is also termed as callus. This tissue develops for protecting the injured surface.
