List different plant hormones nd their functions

Here are some major plant hormones and their functions:

• Auxins: Primarily involved in cell elongation, root formation, fruit development, and phototropism (bending towards light). They are synthesized in young leaves and developing seeds.

• Gibberellins (GAs): Promote stem elongation, seed germination, flowering, and fruit development. They are important for breaking dormancy in seeds and buds.

• Cytokinins: Stimulate cell division (cytokinesis), cell differentiation, and delay senescence (aging) in leaves. They often work in conjunction with auxins.

• Abscisic Acid (ABA): Acts as an inhibitor. It promotes dormancy in seeds and buds, induces stomatal closure in response to water stress, and plays a role in leaf abscission (shedding).

• Ethylene: A gaseous hormone that promotes fruit ripening, flower senescence, and leaf abscission. It also plays a role in triple response in seedlings (shortening, thickening, and horizontal growth) under stress.
