Detailed explanation-1: -Gibberellic acid s (Gibberellins) are naturally occurring plant hormones that are used as plant growth regulators to stimulate both cell division and elongation that affects leaves and stems.

Detailed explanation-2: -Auxins function primarily in stem elongation by promoting cell growth. Indole-3-acetic acid (IAA) is the major naturally occurring auxin and one of the major growth factors in plants. They were the first group of plant growth hormones discovered. Auxins serve dual roles in plants depending on where they are produced.

Detailed explanation-3: -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-4: -An increase in the final cell length contributed to the growth response after 7 h of GA3 application. Our results are consistent with the hypothesis that gibberellin first promotes cell elongation in the intercalary meristem and that cell division is stimulated as a result of cell-growth.

Detailed explanation-5: -Gibberellins are used by scientists to raise their height and cause more cell division, allowing for more longitudinal growth. Gibberellins are one of the oldest plant hormone classes. These are crucial for seed dormancy to be broken and for shoot growth to begin. Gibberellin promotes cell division and lengthening.
