Plant hormones include abscisic acid, auxin, gibberellins, ethylene, salicylic acid, cytokinins, strigolactones, nitrous (nitric) oxide and brassinosteroids. Plant tolerates the environmental stresses with the help of plant hormones.
Plant hormones are also called phytohormones which simply known as signal molecules produced with in plants in low concentration. Phytohormones occur in all plants in the plant kingdom i.e. from algae to higher plants with same function.
Plant hormones controls plant growth and development through embryogenesis and pathogen defence, stress tolerance, organ size regulation and reproductive development. Compare to animals, each plant cell is capable of producing hormones.
