write the names and function of four plant hormones
Answers
Answer:
The four plant hormones and their functions are as follows:
- Auxin: It promotes cell enlargement and cell differentiation in plants.
- Gibberelins: It breaks the dormancy in seeds and buds.
- Cytokinins: It promotes cell division in plants.
- Abscisic acid: It promotes closing of stomata.
plant hormones identified five major classes: abscisic acid, auxins, cytokinins, ethylene and gibberellins..
let me explain you in detail
Abscisic Acid- has important roles in seed development and maturation.
AUXINS-Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips.
Cytokinis- cytokinins are plant hormones that influence not only numerous aspects of plant growth, development and physiology, including cell division, chloroplast differentiation and delay of senescence but the interaction with other organisms, including pathogens.
Ethylene- ethylene in a plant growth regulator that acts as a trace level of entire plant life by regulating and stimulating the opening of flowers, fruit ripening and shedding of leaves.
Gibberellins- Gibberellins are a group of plant hormones responsible for growth and development. They are important for initiating seed germination .
