Those organisms which are composed of only one cell and have no distinct nucleus and organelles are termed as archaea. The phenomena they undergo in order to reproduce are binary fission and budding. None of the species of archaea is known that produces spores. These organisms are different from that of bacteria as analyzed by their RNA sequences.
The members belonging to the domain of archaea have an ability to form methane from CO2 and H2. Some are also capable of carrying out the process of photosynthesis but do not release oxygen. These organisms are widely found in anaerobic, saline and acidic regions.
