Cytokinins are the plant hormones that promote cell division and cell differentiation in the plant root and shoot system. These are mostly detected in all thorny plants, and other organisms like mosses, fungi, bacteria, and insects. The hormones are mainly produced at the meristem of the roots, and there are around 200 different varieties in both natural and synthetic forms. It might promote cell division, but also maintain the level of protein that is essential for mitosis. The process of mitosis helps to replace the damaged cells daily, which further promotes growth. So, it also promotes cell development and growth that affects apical dominance and leaf senescence.
