A student was doing an experiment on increasing the cell division among plants. She asked her supervisor to suggest the specific plant hormone for the same. Had you been her Supervisor, which plant hormone would you suggest ? Correct Answer Cytokinin

The correct answer is Cytokinin.

  • Cytokinins (CK) are a class of plant growth substances (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots.
    • They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.

Additional Information

  • Gibberellins (GAs) are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence.
    • GAs are one of the longest-known classes of plant hormones.
  • Abscisic acid is a sesquiterpene, which has important roles in seed development and maturation, in the synthesis of proteins and compatible osmolytes, which enable plants to tolerate stresses due to environmental or biotic factors, and as a general inhibitor of growth and metabolic activities.
  • Auxin is a key regulator of plant growth and development, orchestrating cell division, elongation and differentiation, embryonic development, root, and stem tropisms, apical dominance, and transition to flowering.
