    auxin is found on the shoot of plant so when light is added the auxin on light side  move to darker side and become acidic causing the expansions of cell on the darker side . this is called cell elongation. There is also a scenario where we remove the the shoot  the plant, it doesnt bent because auxin is removed. Also when we cover the upper side of the shoot it causes auxin to move down thereby making cell of the plant to elongate and the plant remain grow straight.
