The sunflower. When a stalk grows more on one side than the other, it will curl toward the shorter side; that's how curly hair curls! In the case of the sunflower, growth on the western side of the stalk during the night causes the flower to nod toward the east where it meets the rising sun. Then the eastern side overtakes the western side during the day, causing the flower to "follow" the sun.

The sunflower in the picture at right was grown by Dr. Shapiro. You can tell that it's facing the sun by the light on the trees. This flower inspired a poem (caveat lector: I'm no Zachary).
