Detailed explanation-1: -Indole-3-acetic acid is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins and has been the subject of extensive studies by plant physiologists.
Detailed explanation-2: -Plants produce natural auxins such as Indole-3-acetic acid (IAA) and Indole butyric acid (IBA). Natural auxins are found in growing stems and roots from where they migrate to their site of action. Naphthalene acetic acid (NAA) and 2, 4-dichlorophenoxyacetic (2, 4-D) are examples of synthetic auxins.
Detailed explanation-3: -Insulin is a hormone secreted by the pancreas. It is not a plant hormone. The phytohormone (plant hormone) cytokinin is responsible for plant cell division. Cytokinins cause increased cell division (cytokinesis) by stimulating the process of mitosis.
