Answer:

Functions of Plant Hormones

1) Auxin---)

  • Auxins promote stem elongation, inhibit growth of lateral buds They are produced in the stem, buds, and root tips.
  • Example: Indole Acetic Acid.  
  • Auxin is a plant hormone produced in the stem tip that promotes cell elongation.

2) cytokinin--)

  • Cytokinins are plant hormones that cause increased cell division by stimulating the process of mitosis.
  • They are made naturally by plants but have been synthesized by humans.
  • Increased mitosis results in plant growth and the formation of shoots and buds, as well as the development of fruits and seeds.

3) Gibberellin--)

  • 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.

4) Abscisic Acid----)

  • Abscisic acid owes its names to its role in the abscission of plant leaves.
  • In preparation for winter, ABA is produced in terminal buds.
  • This slows plant growth and directs leaf primordia to develop scales to protect the dormant buds during the cold season.
  • ABA also prevents loss of seed dormancy.

5) Ethylene---)

  • Ethylene serves as a hormone in plants.
  • It acts at trace levels throughout the life of the plant by stimulating or regulating the ripening of fruit, the opening of flowers, and the abscission (or shedding) of leaves.
