What to Focus On

  • Plant growth regulators are also called plant hormones or phytohormones.
  • They are organic substances produced in one part of the plant body and act in another part.
  • They are mainly transported through phloem.

  • Auxins were the first plant hormones to be discovered.
  • Auxins are produced by growing tips of stem and root.
  • IAA is the most abundant and powerful naturally occurring auxin.

  • Tropic movement is growth in response to a unilateral stimulus.
  • Shoot is positively phototropic and root is negatively phototropic.
  • Roots are positively geotropic and stems are negatively geotropic.

Common Mistakes to Avoid

Auxin is a growth inhibitor because it controls plant growth.

Indole butyric acid, naphthalene acetic acid, and 2,4-D are natural auxins like IAA.

Apical dominance means lateral buds control the apical bud.
