AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Cytokinin — found in greater concentration in meristematic tissue (actively dividing regions); it promotes rapid cell division, helping in growth of shoots and roots.
The question asks for ONE hormone, its tissue location, and its role — all in one line. Cytokinin is the textbook answer (it appears directly in the Exercise MCQ in the source). Meristematic tissue is where cell division actively occurs, and cytokinins are produced and act there. Examiners expect the hormone name, tissue type, and a brief function — don't mix up cytokinin (cell division) with auxin (cell elongation).
