Cytokinin chemical structure
WebCytokinin comes from the word cytokinesis, which means cell division. You will learn about cytokinesis, specifically mitosis, in Chapter 13. Cytokinins promote cell division, where one cell splits and two new daughter cells are formed. Cytokinins are important regulators of plant growth and development.
