Sunflowers Quiz – Faces That Follow the Sun

Sunflowers are tall annual plants native to North America, where Native Americans domesticated them thousands of years ago. Their large heads are actually made of hundreds of tiny flowers called florets, which turn into seeds.

Young sunflowers track the Sun from east to west each day, then turn back at night. As they mature, most stop moving and face east, which warms the flower heads in the morning and attracts more pollinators. Their seed spirals follow the Fibonacci sequence.

Sunflowers are grown worldwide for seeds and oil, with Ukraine and Russia among the top producers. Vincent van Gogh made them famous in art, and scientists have used them to absorb pollutants from contaminated soil and water.
