Explanation
Plant hormone "AUXIN" is indole Acetic Acid. Indole-3-acetic acid (IAA) is a naturally occurring plant hormone and a member of the auxin class of phytohormones. Auxins, including IAA, play a crucial role in regulating various aspects of plant growth and development. IAA is often considered the primary and most widely studied auxin in plants. IAA promotes cell elongation in the growing tips of plant shoots, stems, and roots. It helps cells to expand and increase in size, leading to the growth of plant organs.IAA is involved in apical dominance, where the apical bud (the bud at the tip of the shoot) inhibits the growth of lateral buds.
