Cytokinins promote cell division in plants and are present in greater concentrations in areas of rapid cell division, such as in fruits and seeds.
What is the role of cytokinins in plant physiology, and in which plant regions are they found in higher concentrations?

Cytokinins play a crucial role in plant physiology, promoting cell division, shoot and root growth, and delaying senescence. They are found in higher concentrations in regions where active cell division is essential, such as in growing shoot tips, root tips, and developing fruits. Cytokinins work in concert with auxins, maintaining a balance that regulates various aspects of plant development. By stimulating cell division, cytokinins contribute to the formation of new tissues and organs, ensuring proper growth and differentiation in different plant regions.
