Sunflowers are fascinating little specimens of nature, and they allow us to see firsthand that plants are not the static beings we believe they are. These particular flowers actually look toward the sun as it rises in the east and follow it across the sky until it sets in the west.
Continuously facing towards the east also helps the flowers to heat up quickly. This gives them an advantage in pollination, as warm flowers attract insects. Therefore, in the plant's interest, the flower always faces the sun and is therefore always clearly visible to these important pollinators.
