Auxin promotes both cell division and cell growth, while cytokinin promotes only cell division.
Higher concentration of auxin and low concentration of cytokinin favours root formation.
Higher concentration of cytokinin and low concentration of auxin favours shoot formation. Moderate concentration of auxin and cytokinin favour callus formation.

Q. In callus culture, shoots can be induced by the supply of
