How Do Sunflowers Face The Sun?

The video explores the fascinating phenomenon of heliotropism in sunflowers, where they track the sun from east to west during the day. This behavior is driven by the plant's circadian rhythm and differential growth rates on either side of the stem. Research shows that sunflowers tied to prevent movement have reduced growth, and mature sunflowers face east to attract more pollinators. The video concludes with a call to action for viewers to engage with the channel.

What observations did researchers make when sunflowers were prevented from moving towards the sun?
