Detailed explanation-1: -Auxins are produced in the apex of stem and root tips and they promote apical elongation of stem along with inhibiting growth of axillary buds.
Detailed explanation-2: -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.
Detailed explanation-3: -In addition to being made in the shoots, auxin is also made in the roots (Muller et al. 1998; Ljung et al.
Detailed explanation-4: -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-5: -Final answer: Cytokinins are produced in root tips and germinating seeds in large amounts.
