In animals, there are special glands secreting hormones, whereas there are no glands in plants. Where are plant hormones formed? How are the hormones translocated to the site of activity?
Ans.
Plant hormones are produced by individual cells in the regions where they are essential by the plants. To take an example, auxin is synthesised in the cells where there are growing apices. The vascular system of plants is where plant hormones are translocated through. Other examples include the Abscisic acid produced in many parts of plants, which is transported through diffusion and transport channel.
