In a tissue culture experiment,parenchyma tissue was used as a source to develop a new plant.However,the parenchyma tissue did not have enough hormones,so a group of undifferentiated cells,called callus,formed.Which one of the following could happen if the callus was supplemented with specific hormones?
A)Callus supplemented with auxin would produce shoot buds.
B)Callus supplemented with cytokinin would produce leaves.
C)Callus supplemented with auxin and cytokinin would produce root and shoot buds,respectively.
D)Callus supplemented with auxin and cytokinin would produce shoot buds and roots,respectively.

Callus cells are totipotent, meaning they have the ability to differentiate into any type of cell. Supplementation with auxin and cytokinin is commonly used in tissue culture to promote the development of roots and shoot buds, respectively. Therefore, if the callus is supplemented with both hormones, it is most likely that it would develop root and shoot buds, respectively.
