Question

Describe the structures and mechanism of action of cytokinins.

Answer 1

Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell's growth, development, differentiation, affecting apical dominance, leaf senescence, and axillary bud growth. Cytokinins are plant hormones that cause increased cell division by stimulating the process of mitosis. They are made naturally by plants but have been synthesized by humans. Increased mitosis results in plant growth and the formation of shoots and buds, as well as the development of fruits and seeds.
