They account for over fifty per cent of human energy and protein needs, and cereal plants occupy two-thirds of all cultivated land.The functions of the GA depend on the type that is present and on the plant species. It also stimulates cell division and elongation causing stems to grow. Respond to longer days and stimulate the growth of flowering stems.
