Options:
Answer:
D
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.
