Cytokinin
Cytokinin is the plant hormone that induces cell division in plants. Here is an explanation of how cytokinin functions in regulating cell division:

Role of Cytokinin in Cell Division
- Cytokinin promotes cell division by stimulating the activity of the cell cycle regulatory proteins.
- It plays a crucial role in the process of cell division by promoting the expression of genes involved in cell proliferation.
- Cytokinin also influences the differentiation of cells by regulating the balance between cell division and cell growth.

Mechanism of Action
- Cytokinin exerts its effects by binding to receptors on the cell membrane, leading to the activation of signal transduction pathways.
- This activation triggers a cascade of events that ultimately result in the stimulation of cell division.
- Cytokinin also interacts with other plant hormones, such as auxin, to coordinate growth and development processes in plants.

Effects on Plant Growth
- In addition to promoting cell division, cytokinin also plays a role in regulating various aspects of plant growth, including shoot and root development.
- It helps in the formation of new tissues and organs, as well as in the response of plants to environmental stresses.
In conclusion, cytokinin is a key plant hormone that regulates cell division and growth in plants. Its ability to stimulate cell proliferation and differentiation makes it essential for the proper development and functioning of plant tissues.
