What is the function of cytokinin in plants?

Cytokinins are a class of plant hormones that play a crucial role in promoting cell division and growth in plants. They primarily encourage the process of cytokinesis, which is the division of the cytoplasm in a cell, leading to the formation of two daughter cells. This function is essential for the growth of new tissues and organs, such as leaves, stems, and roots. Cytokinins are produced in the root tips and are transported upward through the plant, influencing various stages of growth and development.

The correct answer emphasizes this role in facilitating cell division for the development of new plant organs, which is vital for overall plant growth and productivity. This aspect of cytokinin action is particularly important when considering how plants respond to environmental stimuli by growing new structures that can help improve their chances of survival and reproduction.
