HERE IS UR ANS BUDDY...
An auxin, is a plant growth hormone that helps regulate shoot growth. ... But when sunlight varies, auxin is broken down on the sunnier side of the stem. The higher concentration of auxin on the shady side causes the plant cells on that side to grow more so it bends toward the light.
