Question

What are the functions of:
(i) Auxins
(ii) Gibberellins
(iii) Cytokinins (iv) Abscisic acid​

Answer 1

Answer:

1. Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation.
2. Function of Gibberellins
3. Gibberellins are growth hormones that stimulate cell elongation and cause plants to grow taller. Gibberellins also have a role in other plant processes, such as stem elongation, germination, flowering, and fruit ripening

Answer 2

Answer: Phyto hormones (Plant hormones) are the chemicals produced by plants the co-ordinate their growth and functioning

There are 5 phyto hormones:-

i.) Auxin :- It helps in the growth of stem

ii.) Gibberellins :- They promote germination of seeds

iii.) Cytokinin :- They help in cell division

iv.) Abscisic acid :- It inhibits growth and promotes falling of leaves
