Expert Answer
- Gibberellins are synthesised in plastids in plants. They exert their effect on growing parts of the plants.
- Cytokinins are produced in the root apical meristems. Cytokinins are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.
- Auxins are synthesized in the stem apexes. Auxin induces shoot apical dominance.
