Plant cells that are on the shadier side of the plant grow longer due to the plant hormone auxin. Direct sunlight (the sunny side) causes auxin to break down. This makes the plant bend toward the light. Udnder normal light conditons auxin is spread out evenly in the plant, causing it to go straight.

Chemical called auxin which promotes plant cell growth, sunshine destroys auxin so there is less on the side of the plant on which the sun shines so the opposite side grows more and bends towards the light. https://youtu.be/3q6C8coA5yc
