Expert Answer:

The important plant hormones are auxins, cytokinins, gibberellins, abscisic acid and ethylene.

Auxins promote stem elongation (by promoting cell elongation) and inhibit growth of lateral buds (maintains apical dominance).

Cytokinins promote cell division.

Gibberellins stimulate cell division and elongation in plants.

Abscisic acid inhibits growth. It promotes seed dormancy by inhibiting cell growth. Its effects include wilting of leaves.

Ethylene is a gaseous plant hormone that stimulates fruit ripening and the dropping of leaves.
