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. If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people.
A thunderstorm is a storm where you hear thunder and see lightning. Usually there is heavy rain in a thunderstorm. Thunderstorms are electric storms. When there is about to be a thunderstorm, a cumulonimbus cloud forms, often in a clear blue sky. (When a cloudâs name ends in nimbus, it means rain or snow is falling from the cloud.) The cloud increases in size and begins to build up peaks, which become very dark.
