Cell Auxins Gibberellins Increase Length Division Loosen Walls

Both auxins and gibberellins promote stem elongation by affecting cell length and loosening cell walls. However, auxins stimulate apical meristems, while gibberellins stimulate intercalary meristems and cell division.

Both auxins and gibberellins increase stem length by affecting cell length and loosening cell walls, but auxins stimulate apical meristems while gibberellins stimulate intercalary meristems and cell division.

Front Compare the action of gibberellins and auxins in the growth of stems.
Back Auxins vs gibberellins:
  • Both increase stem length, cell length and are acidic
  • Auxins have no effect on cell division (they loosen cell walls allowing for elongation) & they sitmulate apical meristems
  • Gibberellins increase cell division, loosen cell walls and stimulate intercalary meristems
