Vedclass · Answer

(D) The bending of a plant towards light is known as phototropism. This phenomenon is primarily controlled by the plant hormone $Auxin$. When light falls on a plant from one side,$Auxin$ migrates to the shaded side of the stem. $Auxin$ promotes cell elongation. Since there is a higher concentration of $Auxin$ on the shaded side,the cells on that side elongate more rapidly than the cells on the illuminated side. This differential growth causes the stem to bend towards the light source.
