Bacteria

Bacteria Bacteria have been around for about 3.5 billion years. Like all cells, bacteria contain DNA, but the DNA in bacteria is different then other organisms, it’s arranged in a single circular chromosome while most cells have several rod shaped chromosomes. Some bacteria also have flagella. This makes the bacteria move by beating in a propeller- motion. Bacteria can be classified in many different ways. There are also bacteria that need oxygen called aerobic bacteria and bacteria that don’t need oxygen called anaerobic bacteria. Different bacteria contain different components, While some contain endospores or pili others may contain starch granules or ribosomes and enzymes. Bacteria come in three basic shapes, rod shaped bacteria, which are called bacilli, round shaped bacteria, which are called cocci, and spiral shaped bacteria called spiriochetes. The possibilities are endless, as are the different types of bacteria.
