Which of the following hormone, in combination with auxin, stimulates cell division in plants and determines the course of differentiation mainly?

Options

  1. AEthylene
  2. BIAA
  3. CGibberellins
  4. DCytokinin

Correct answer

D. Cytokinin

Step-by-step solution

The cytokinin hormones promote cell division and tissue growth and depend upon the presence of auxins to determine the extent of their activity. When the ratio of cytokinins to auxins is relatively high, stem and leaf growth is stimulated. Auxins and cytokinins are the best documented as impinging directly on cell cycle control.
