BOTANY

Detailed explanation-1: -Cytokinins promote cell division, cell growth and differentiation along with auxin. Ethylene is responsible for fruit ripening. Abscisic acid helps the plant to sustain in adverse conditions. Gibberellins enable the plants to grow taller.

Detailed explanation-2: -Cytokinins are essential plant hormones. By stimulating cell division, they regulate shoot meristem size, leaf primordia number, and leaf and shoot growth. They can stimulate both the differentiation and the outgrowth of axillary buds. The cytokinins can mediate axillary bud release from apical dominance.

Detailed explanation-3: -Cytokinins stimulate cell division and are found in the regions of the plant where rapid division is taking place. They have a highly synergistic effect in concert with auxins, and the ratios of these two groups of plant hormones affect most major growth periods during a plant’s lifetime.

Detailed explanation-4: -The hormones auxin and cytokinin are key regulators of plant growth and development. As they are active at minute concentrations and regulate dynamic processes, cell and tissue levels of the hormones are finely controlled developmentally, diurnally, and in response to environmental variables.

Detailed explanation-5: -Auxins and cytokinins are classes of plant hormones that regulate plant growth. Their main difference lies in their two most important respective functions. Cytokinin is required for cell division – in other words, the production of new cells.
