Detailed explanation-1: -In the shoots, auxin stimulates cell elongation and thus high concentrations of auxin promote growth (cells become larger)
Detailed explanation-2: -The plant hormone auxin is well known to stimulate cell elongation via increasing wall extensibility. Auxin participates in the regulation of cell wall properties by inducing wall loosening.
Detailed explanation-3: -What is the function of auxin in plants? 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-4: -Auxin is a key regulator of plant growth and development, orchestrating cell division, elongation and differentiation, embryonic development, root and stem tropisms, apical dominance, and transition to flowering.
