Detailed explanation-1: -Auxins are also important in regulating the fall of leaves and fruits.
Detailed explanation-2: -Auxin hormone saves the crops from falling i.e regulates the fall of leaves and fruits. In the presence of auxins, cytokinin hormones help in cell division and development. The most common naturally occurring plant hormone of the auxin class is acetic acid. The transport of auxin in plants is polar.
Detailed explanation-3: -Answer. Answer: Auxins, cytokinin and gibberellins largely affect the plant growth.
Detailed explanation-4: -Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell’s growth, development, differentiation, affecting apical dominance and delay in leaf senescence.
