The student is looking for a plant hormone that can increase cell division among plants. Let`s analyze each option to determine which plant hormone would be the most suitable.
Option 1: Abscisic acid is primarily responsible for regulating plant response to stress, slowing down growth, and promoting seed dormancy. It does not have a significant role in promoting cell division. Therefore, Abscisic acid is not the correct option.
Option 2: Gibberellins are hormones that promote stem elongation, flowering, and seed germination. They also play a role in cell division, but their main function is not to specifically increase cell division. While Gibberellins can indirectly influence cell division, their primary role is not directly linked to increasing cell division among plants. Thus, this option is not the best choice either.
Option 3: Cytokinins are plant hormones that have a direct role in promoting cell division. They play a crucial role in cell differentiation, shoot formation, and overall plant growth. Therefore, Cytokinins would be the most appropriate choice as they specifically promote cell division among plants.
Option 4: Auxin is a plant hormone that primarily regulates plant growth and development by promoting cell elongation. While Auxin can indirectly influence cell division, it
