BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Cytokinins are plant hormones which promotes cytokinesis or cell division. It also helps in opening of stomata, delaying ageing in leaves, etc.

Detailed explanation-3: -Growth hormone stimulates cell division, protein synthesis, and growth in all cells. Cell division is the process by which the mature cell can divide into daughter cells of two where there is a resemblance of parental characters. Growth hormone (GH) is secreted by the anterior pituitary and stimulates growth in humans.

Detailed explanation-4: -Cytokinin are adenine derivatives. They 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.
