Solution
Cytokinin:
A type of plant hormone that promotes cell division in plant roots and shoots is called cytokinins.
It is synthesized in the apices of roots and developing shoot buds where rapid division occurs.
It also promotes root apical dominance and regulates root gravitropism along with auxin.
