Answer 2

Answer:

There are 5 types of Phytohormones:-

1. Auxins - Promotes cell elongation and growth of stem and root

                 Causes apical dominance

                 Induces rooting on stem cutting

2. Gibberellins - Induces pathenocarpy (development of fruits without seeds)

                         It's application overcomes the genetics dwarfism

                          Breaks up the dormancy of seeds

3. Cytokinins - Promotes cell division and enlargement

                         Promotes the germination of seeds

4. Abscisic acid - Inhibits cell growth and cell division.

                            Causes dormancy of buds & leaves

                            Induces wilting of leaves and closure of stomata

5. Ethylene - It plays a role in ripening of fruits
