NEET BIOLOGY

Detailed explanation-1: -Gibberellins are plant growth regulators that facilitate cell elongation, help the plants to grow taller. They also play major roles in germination, elongation of the stem, fruit ripening and flowering.

Detailed explanation-2: -Auxin is produced by the tip of the stem and helps in the elongation of cells. It promotes cell elongation, root growth and shoot growth.

Detailed explanation-3: -Gibberellins promote growth in different ways. These hormones are mainly involved in controlling and promoting stem elongation, flowering, and leaf expansion as well as seed germination. They are used in suspension cultures to enhance the growth of cells.

Detailed explanation-4: -Gibberellins stimulate cell elongation by altering the rheological properties of the cell wall; as a consequence, the water potential of the cell is lowered allowing for water uptake and therefore an increase in cell volume.

Detailed explanation-5: -Gibberellins are a type of plant growth regulator (PGR) that play an important role in plant growth. They play vital roles in internode elongation, seed germination, delaying senescence, parthenocarpy, flowering, etc.
