Vedclass · Answer

(D) Phototropic curvature in plants is primarily caused by the uneven distribution of the hormone $Auxin$ (specifically $Indole-3-acetic$ $acid$ or $IAA$).When a plant is exposed to unilateral light,$Auxin$ migrates to the shaded side of the stem.This higher concentration of $Auxin$ on the shaded side stimulates greater cell elongation compared to the illuminated side.As a result,the stem bends towards the light source,a phenomenon known as phototropism.
