Solution

Cytokinin:

  1. Cytokinin is a phytohormone or a plant growth regulator hormone.
  2. It helps to promote mitotic cell division and positively regulates cell division.
  3. Apart from this, it also helps in plant growth.
  4. Auxin is a phytohormone that promotes apical dominance.
  5. Cytokinin acts antagonistically to auxin and helps the plant to overcome apical dominance.
  6. Instead, it promotes lateral shoot growth and development.
