This hormone stimulates cell division.

Here is something that I found: Gibberellins stimulate cell division and elongation but act more slowly than auxins.Cytokinins stimulate mitosis in actively developing plant parts. Ethylene speeds ripening. Abscisic acid inhibits the growth-inducing effects of other hormones. Hope this helped ☻

We can use solar powered cars or ride bikes instead of cars that burn fossil fuels
