Question

Cytokinin includes:

• A. Kinetin, zeatin, BAP
• B. $G{A}_3$, IBA, Kinetin
• C. Zeatin, $G{A}_3$ , BAP
• D. IAA, Zeatin, kinetin

Answer 1

The correct option is A Kinetin, zeatin, BAP

Cytokinins (CK) are a class of plant growth substances (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots. There are two types of cytokinins: adenine-type cytokinins represented by kinetin, zeatin, and 6-benzylaminopurine (BAP), and phenylurea-type cytokinins like diphenylurea and thidiazuron (TDZ).
$G{A}_3$ is another phytohormone, gibberellin. IBA and IAA are forms of auxin.
