Professor PC Thomas Classes · Answer

(c) : Plant hormones are chemicals present in plants which help to coordinate growth, development and responses to stimuli and environment. For example, auxins, gibberellins and cytokinins. Abscisic acid are different plant hormones. Abscisic acid or ABA is a plant hormone or phytohormone which acts as growth inhibitor. It promotes dormancy in seeds and buds, abscission (falling of leaves) and senescence in leaves and thus inhibits growth of plant. Cytokinins promote cell division.
