Plants have a hormone called auxin in them. When a plant is exposed to light and shade this hormone(auxin) reacts. For example: If light falls on the right hand side of the plant, the left hand side would be in the shade. This makes the auxin expand in the shaded area, causing the plant to grow towards the light.
