What are the characteristic of most bacteria?

All bacteria are prokaryotic, meaning that they lack organelles and a nucleus, where the DNA is contained. Instead of a nucleus, the DNA is generally found in a nucleoid region in the center of the cell.





All bacteria are single-celled. Some types of bacteria form colonies, where there are clumps or chains of single-celled bacteria.





All bacteria have a cell membrane and a cell wall. Inside the cell, you will find cytoplasm and ribosomes, as well as the nucleoid region of the DNA. In addition, bacteria have both bacterial cilia and flagella (used in movement).





Bacteria reproduce asexually through fission, where the cell splits, usually in half.





Bacteria are classified into two different domains: Domain Bacteria and Domain Archaebacteria. All bacteria are classified in the Kingdom Monera.

What are the characteristic of most bacteria?
Bacteria are microscopic organisms whose single cells have neither a membrane-bounded nucleus nor other membrane-bounded organelles like mitochondria and chloroplasts. Another group of microbes, the archaea, meet these criteria but are so different from the bacteria in other ways that they must have had a long, independent evolutionary history since close to the dawn of life. In fact, there is considerable evidence that you are more closely related to the archaea than they are to the bacteria!
