Question

What are the major differences among auxins and gibberellins?

Answer 1

Auxins are plant hormones that mainly promote cell elongation, root formation, apical dominance, and tropic movements. They are produced in the growing tips of shoots and roots. Gibberellins are plant hormones that promote stem elongation, seed germination, flowering in some plants, and fruit growth. They are produced in young leaves, embryos, and seeds. Thus, auxins mainly regulate root growth and tropisms, whereas gibberellins mainly promote stem growth and seed germination.
