Vedclass · Answer

(A) Phototropism is the growth of an organism in response to a light stimulus.In plant shoots,phototropism is primarily caused by the unequal distribution of the hormone $Auxin$.When a shoot is exposed to light from one side,$Auxin$ migrates to the shaded side of the stem.This higher concentration of $Auxin$ on the shaded side stimulates greater cell elongation in that region compared to the illuminated side.As a result,the shoot bends towards the light source.
