Vedclass · Answer

(A) The term $Callus$ refers to an unorganized or undifferentiated mass of cells that develops from explants (plant tissue) when grown on a nutrient medium under sterile conditions.To induce the formation of callus and support its growth,the culture medium is supplemented with specific plant growth regulators,primarily $Auxin$ and $Cytokinin$.Since the addition of these hormones is the specific reason why the undifferentiated mass (callus) is formed and maintained in tissue culture,$R$ provides the correct explanation for $S$.

$S$ - Statement: An undifferentiated mass of cells in a culture is called callus.
$R$ - Reason: Auxin and cytokinin are added as growth regulators in the culture medium for callus induction.
