Throughout 12U Biology this year we have learned about many different enzymes and proteins which both humans and plants possess. This piece of writing's purpose is to touch on 3 plant hormones which we do not touch on and to explain how the hormones carry out their specific actions. The three hormones that are going to be covered are cytokinin, abscisic acid, and brassinosteroids. To begin, what do cytokinins do in a plant? cytokinins were found in the late 1950s by F. Skoog and C.Miller, and what they found was that cytokinins influenced cell division in plants. What this means is that the cytokinin hormone plays a huge role in plant morphogenesis, this is just a fancy word for growth, specifically the growth in shoots and roots. Cytokinin
