Bacteria – tiny living things


Bacteria are small unicellular living things, that can be found everywhere. Most bacteria can be seen only with a microscope. Only viruses are smaller. There are many species of bacteria, some of them can live in extreme environments.
Bacteria take in food and send out waste through their cell walls. Most bacteria reproduce by dividing down the middle to form two separate cells. Billions of bacteria may form from a single bacterium in only 24 hours.
For breathing most bacteria need air and are called aerobic. But there are bacteria that live without air, anaerobic, and the oxygen in the air is poison for them. They feed on organic substances.

The Dutch merchant and amateur scientist Anton van Leeuwenhoek was the first to observe bacteria and other microorganisms. He described bacteria and other microorganisms in a series of letters to the Royal Society of London between 1674 and 1723.
Many bacteria cause illness, some help digest sewage in treatment plants, or produce the alcohol in wine, beer and liquors.
