BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cytokinins promote lateral and adventitious shoot growth and are used to initiate shoot growth in culture and also help in overcoming apical dominance induced by auxins.

Detailed explanation-2: -Auxins. Auxins are a family of hormones found in plants. Auxins are mostly made in the tips of the shoots and roots, and can diffuse to other parts of the shoots or roots. They change the rate of elongation in plant cells, controlling how long they become.

Detailed explanation-3: -Auxins are a family of plant hormones. They are mostly made in the tips of the growing stems and roots, which are known as apical meristems, and can diffuse to other parts of the stems or roots. Auxins control the growth of plants by promoting cell division and causing elongation in plant cells (the cells get longer).

Detailed explanation-4: -The plant hormone auxin affects cell elongation in both roots and shoots. In roots, the predominant action of auxin is to inhibit cell elongation while in shoots auxin, at normal physiological levels, stimulates elongation.

Detailed explanation-5: -Root-generated Auxin Contributes to Root Development.
