Vedclass · Answer

(D) The phenomenon of a plant bending towards a light source is known as phototropism. This occurs because the hormone $Auxin$ is synthesized at the shoot tip. When light falls on one side of the plant, $Auxin$ migrates to the shaded side. $A$ higher concentration of $Auxin$ on the shaded side promotes greater cell elongation in that region compared to the illuminated side. Consequently, the differential growth causes the plant stem to bend towards the light source.
