They can move within the plant and control various processes even in small amounts. Key plant hormones include Auxin, Gibberellin, Ethylene, Abscisic acid, and Cytokinin. These hormones play roles in plant growth and development, like cell growth, making seeds, flowering, and leaf shedding.<\/p>\n<p><strong>Q.
