Question

Which one of the following hormones regulates cell division in plants? A. auxin (IAA. B. ethylene C. gibberellins D. cytokinins

Answer 1

cytokinin's regulates cell division in plants.

• A group of plant hormones known as cytokinins (CK) encourages cytokinesis, or cell division, in the roots and shoots of plants.
• A group of plant hormones known as cytokinins (CK) encourages cytokinesis, or cell division, in the roots and shoots of plants.
• They influence apical dominance, axillary bud formation, and leaf senescence in addition to being largely involved in cell proliferation and differentiation.
• When leaf cell development is in the proliferation stage or the expansion stage, cytokinins, in the appropriate order, promote cell division and boost cell expansion.
• Cytokinins decrease the buildup of sugar during leaf senescence, boost the production of chlorophyll, and extend the photosynthetic period. Examples include benzyl adenine, kinetin, and zeatin.
