On a molecular level, the structure of chlorophyll is very similar to heme, which is a part of hemoglobin present in human blood. Heme, which is what makes blood appear bright red once exposed to oxygen, is bound to proteins forming hemoglobin.
Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous.
