Bacteria - Wikipedia- bacteria and archaea ,Bacteria (/bækˈtɪəriə/ (listen); common noun bacteria, singular bacterium) are a type of biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on ...Introduction to the ArchaeaHowever, biochemically and genetically, they are as different from bacteria as you are. Although many books and articles still refer to them as "Archaebacteria", that term has been abandoned because they aren't bacteria -- they're Archaea.



Archaea vs Bacteria - Difference and Comparison | Diffen

Archaea (/ ɑːr ˈ k iː ə / (listen) or / ɑːr ˈ k eɪ ə / ar-KEE-ə or ar-KAY-ə) (singular archaeon) constitute a domain of single-celled organisms.These microorganisms lack cell nuclei and are therefore prokaryotes.Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this classification is outmoded.

Three Domain System

Like bacteria, archaea are prokaryotic organisms and do not have a membrane-bound nucleus.They also lack internal cell organelles and many are about the same size as and similar in shape to bacteria. Archaea reproduce by binary fission, have one circular chromosome, and use flagella to move around in their environment as do bacteria.
