The hormones that control and coordinate the activities in plants are called plant hormones.
The four types of plant hormones are:
(i) Auxins: It promotes cell enlargement and cell differentiation in plants.
(ii) Gibberellins: It helps in breaking the dormancy in seeds and buds.
(iii) Cytokinins: It promotes cell division in plants.
(iv) Abscisic acid: It promotes the dormancy in seeds and buds.
