Answer
Auxins
Reason — The plant hormone auxin controls the growth of shoots by stimulating cell elongation. When light falls on one side of a plant shoot, auxin accumulates on the side away from the light, causing the cells there to grow longer and this unequal growth bends the shoot toward the light.
