NEET BIOLOGY

Detailed explanation-1: -“Gibberellins are any group of plant hormones that stimulate elongation of the stem, flowering and germination.”

Detailed explanation-2: -The plant hormone gibberellin (GA) controls major aspects of plant growth such as germination, elongation growth, flower development, and flowering time. In recent years, a number of studies have revealed less apparent roles for GA in a surprisingly broad set of developmental as well as cell biological processes.

Detailed explanation-3: -Gibberellins, which are a group of plant hormones responsible for growth and development, are important for initiating seed germination . Low concentrations can be used to increase the speed of germination, and they stimulate cell elongation and cause plants to grow taller. They are naturally produced by seeds.

Detailed explanation-4: -Auxin: Auxin is a plant hormone that promotes growth. It is synthesized at the tip of the shot and on the stem apices and is also produced in the buds, stems and root tips. Auxin promotes cell elongation, helps in the growth of stems etc.

Detailed explanation-5: -Gibberellins promote the formation of flowers on genetically plants in Cannabis whereas ethylene promotes formation of flowers on genetically plants.
