Plants use hydrogen peroxide as sun screen.

Hydrogen peroxide protects plants against sun damage. A new research shows that plants use hydrogen peroxide to control how their cells react to varying levels of light. The hydrogen peroxide is a by-product of photosynthesis in parts of plant cells called chloroplasts. The study by the University of Exeter and the University of Essex is the first to discover where and how the process happens. Its very important for plants to be able to detect how much light there is, so they can use it for photosynthesis. The plants also have to adjust to protect themselves, as high levels of light can damage leaves same as how humans get sunburn on our skin. more
