Solution:

ABA plant hormone is involved in seed and bud dormancy.
Gibberellin is involved in stem elongation, germination, and senescence.
Auxin is involved in maintaining apical dominance and cell elongation. This hormone is produced at shoot tip.
Cytokinin involves cell division which in turn results in elongation and growth.
High concentration of cytokinin induces shoot growth and hight auxin concentration induces root growth. Auxin and Cytokinin together induce shoot and root growth and hence they are widely used in plant tissue culture.
