Explanation:

Hormones, generally, are chemicals produced in a specific part of an organism in order to bring about a physiological change in another part. Hormones produced by plants are classified into the following: Auxins, Gibberellins, Cytokinins, Ethylene, and Abscisic acid. They effect the following major functions in plants:

- Gibberellins: These are hormones produced by plants that stimulate stem elongation, seed germination, and flowering.

- Abscisic acid: These are hormones that regulates survival functions of a plant such as the opening and closing of stomata.

- Cytokinins: These are chemicals/hormones that helps plant cells divide.

- Ethylene: These are hormones that promotes ripening of fruit or blooming of flowers.

- Auxins: These are chemicals or hormones produced in plants that are characterized by their ability to induce cell elongation and cell division in stems.
