Auxin

Ethylene

Cytokinin

Gibberellin

- Auxin:

- Regulates plant growth by stimulating cell elongation, especially in stems.

- Plays a crucial role in the directional growth of plants towards light (phototropism).

- Ethylene:

- A gaseous hormone that influences fruit ripening and leaf abscission.

- Not primarily involved in cell elongation.

- Cytokinin:

- Promotes cell division and growth of lymph tissues.

- Works in tandem with Auxins for cell differentiation and development.

- Gibberellin:

- Stimulates stem elongation and seed germination.

- Plays a role in breaking seed dormancy.
