BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cytokinin (CK), synthesized in the root cap, promotes cytokinesis, vascular cambium sensitivity, vascular differentiation and root apical dominance. Auxin (indole-3-acetic acid, IAA), produced in young shoot organs, promotes root development and induces vascular differentiation.

Detailed explanation-2: -Cytokinins are synthesized in the roots and are usually derived from adenine. They move upward in the xylem (woody tissue) and pass into the leaves and fruits, where they are required for normal growth and cell differentiation.

Detailed explanation-3: -Final answer: Cytokinins are produced in root tips and germinating seeds in large amounts.

Detailed explanation-4: -Cytokinins are produced mainly in meristematic tissue, where most plant growth occurs.

Detailed explanation-5: -Auxin is made in the tip region of the plant stem which is made up of meristematic tissue and this hormone promotes the growth of the plant.
