Answer:
It is due to a an effect known as phototropism.
Explanation:
As we know , plant hormone namely auxin influences cell division.
This hormone has a tendency of going away from light (i.e. it loves shady region).
Therefore , when sun light is coming from one side of a plant , auxin moves in opposite direction and influence cell division which results in bending of the plant towards the sunlight.
