Question
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?
Solution
Plant hormones are produced by individual cells; in regions where they are required by the plants. For example; auxin is synthesized in the cells of growing shoot apices. Plant hormones are translocated through the vascular system of plants. For example; auxin from the shoot apex may get mobilized to the lateral buds or flower buds. Similarly, some plant hormones may be mobilized to senescent parts.
