Sunflowers Shift to Face the Sun

Sunflowers face East in the morning and West in the evening, then return to face East in the evening after the sun goes down. The hormone auxin, which promotes stem growth, is produced more quickly in shaded portions of the plant. Those parts therefore grow more quickly, which cause the head of the sunflower to tilt toward the sun.

Sunflower movement could inspire the development of solar cells that turn to face the sun, using a mechanism similar to that of sunflowers. The example of auxin could inspire a system that collects solar heat without having to use complex circuits.
