How does a sunflower follow the sun across the sky?

🧠 Detailed Explanation (For Older Kids)

Sunflowers have a special behavior called phototropism, which means they grow towards light. As the sun moves across the sky, a sunflower's stem bends so that its flower always faces the sun. This helps the sunflower get more sunlight for making food through photosynthesis. They start the day facing east and follow the sun until it sets in the west!
