Expert Answer:

Auxins are phytohormones, which help to coordinate growth and development in the plant body. Auxin stimulates cell elongation. Together with cytokinins, auxins stimulate cell division. Auxins breaks the root apical dominance induced by cytokinins and induce new root formation. But they induce shoot apical dominanace. Auxins are responsible for causing phototropism, geotropism and hydrotropism. Auxin is also important for fruit growth and delays fruit senescence. Thus auxin is a very important plant hormone.
