The scientific and common names for Archaebacteria are both Archaea, as of 2014. Archaea used to be considered bacteria, but are now considered their own kingdom and domain separately.
Archaea are distinguished as single-celled organisms with no nucleus. They are found in a wide range of environments, including, but not limited to extreme environments, such as salt lakes, deep-sea thermal vents and hot springs. They are also found in oceans, wetlands, soil and even the human body. They reproduce asexually and do not produce spores, unlike some forms of bacteria. They are often mutualist species; but, they do not cause harm to other organisms, unlike pathogenic bacteria or parasitic fungi.Learn More
It is believed that the first organisms to appear on Earth resembled singled-celled life forms known as Archaea, which are similar to bacteria but lack nuclei. Modern-day Archaea can live in extreme environments such as hot springs and deep-sea vents. These conditions replicate some of those on early Earth.Full Answer >
Archaea and bacteria are prokaryotes that lack cell nuclei and membrane-bound organelles, while protists are eukaryotes that possess both of these features. Archaea and bacteria are always single celled, while a small number of protists are multicellular organisms.Full Answer >
Archaea, bacteria, Protista, fungi, viruses and microbial mergers are divisions that contain microorganisms. Most microorganisms are single-celled organisms. Baker's yeast and fission yeast are unicellular microorganisms.Full Answer >
The Archaea, or archaebacteria, are the prokaryotic group most closely related to eukaryotes. This is due to the similarity of genes and metabolic processes that both Archaea and eukaryotes posses. One major similarity are the enzymes involved in transcription and translation.Full Answer >
