Cytokinins are mainly involved in which process?

• A. Seed germination
• B. Photosynthesis
• C. Cell division
• D. Wilting

Answer: (C)

Cytokinins are plant hormones that primarily promote cell division. They stimulate the cell cycle, encouraging DNA synthesis and the production of proteins needed for cells to divide, especially in actively growing tissues. In development, they work with auxins to influence how tissues differentiate, but their main link to this question is driving mitotic activity and tissue growth. That’s why adding cytokinins in plant tissue culture causes callus tissue to divide and can promote shoot formation when paired with the right balance of hormones. They are not the primary drivers of seed germination, photosynthesis, or wilting.
