Question

_______________ in combination with auxin stimulates cell division in plants and determines the course of differentiation.

• A. Cytokinin
• B. Gibberellin
• C. Abscisic acid
• D. Ethylene

Answer 1

The correct option is A

Cytokinin

Cytokinins stimulate cell division and are found in the regions of the plant where rapid division is taking place. They have a highly synergistic effect in concert with auxins, and the ratios of these two groups of plant hormones affect most major growth periods during a plant's lifetime.
