Why Do Sunflowers Follow the Sun?

Some plants move their flowers or leaves towards the light source. This movement is called heliotropism. Heliotropism is the motion of plant parts in response to the direction of the sun, enhancing the photosynthesis process and increasing growth rates.
Sunflowers are one of several plant species that make optimum use of light by tracing the direction of the sun.
