What are blue-green eyelashes?
Blue-green eyelashes, commonly known as cyanobacteria, are one of the simplest, most common and earliest forms of life on the planet. Cyanobacteria's fossils reach 2.8 billion years, the oldest known fossils that exist for more than 2 billion years ago. Unlike other forms of "algae", such as green, red and brown algae, blue-green algae consist of bacteria-no eukaryotic cells. Bacterial cells are about ten times less than eukaryotic cells and lack cores and complex organs (cellular organs).
When blue -green eyelashes first appeared on the scene about 2.8 billion years ago. At a time when blue -green eyelashes developed, the Earth's atmosphere was composed mainly of nitrogen (as today), but another gas of about 25%was carbon dioxide. Blue-green eyelashes were the first forms of life capable of oxygenic photosynthesis to occupy carbon dioxide and sun rays to produce energy, oxygen and water.
After working for about 500 million years, blue-green eyelashes have transformed atmospheric carbon dioxide into most oxygen. This provided a lot for free energy for any subsequent organisms, but killed all anaerobic (air -hate) bacteria that previously dominated the planet. Given the massive extinction, this event is known as an oxygen disaster. The evidence of this event is left in the form of striped iron formations, a rock consisting of strips of oxidized iron compounds alternating with minerals poor in iron, such as slate. These iron compounds were formed when cyanobacteria locked iron in compounds that sank to the seabed.
Cyanobacteria found mainly in the oceans, where they are primary manufacturers and eat many other organs. Source of their name, blue-green eyelashes. The green color comes from chlorophyll in their cells. In the oceans where it is in seawaterAnd carbon dioxide available enough nitrogen is available from the atmosphere, the main limiting factor of their growth is iron. Some scientists have begun to experiment with iron fertilization to increase their growth, which can sequence carbon dioxide from the atmosphere and reduce global warming.
cyanobacteria are also known for their ability to correct nitrogen-or convert it from the form of gas into a solid form-more basic feature of any ecosystem. All organisms need solid nitrogen sources to survive. Other organisms are converted by fixed nitrogen compounds into proteins and nucleic acids.
