Cytokinins (Plant Hormone)

Cytokinins are a class of plant hormones that promote cell division and growth, primarily by stimulating the proliferation of cells in the shoot and root meristems. They also play a crucial role in regulating various physiological processes, including leaf senescence and nutrient mobilization.

Overview

Cytokinins are vital plant hormones that significantly influence plant growth and development. They primarily promote cell division, particularly in shoots and roots, and work in conjunction with other hormones like auxins to ensure balanced growth. Understanding cytokinins is essential for improvin...

Key Terms

Hormone
A chemical substance produced in the body that regulates physiological processes.

Example: Plant hormones like auxins and cytokinins control growth.

Cell Division
The process by which a parent cell divides into two or more daughter cells.

Example: Cytokinins stimulate cell division in plant tissues.

Tissue Culture
A technique for growing plants in a controlled environment using small pieces of plant tissue.

Example: Cytokinins are used in tissue culture to promote growth.

Auxins
A class of plant hormones that promote elongation of cells.

Example: Auxins and cytokinins work together to regulate plant growth.

Signal Transduction
The process by which a cell responds to external signals.

Example: Cytokinins initiate signal transduction pathways to promote growth.
