archaea classification

Archaea are one of the three main domains of life, alongside bacteria and eukaryotes. They are single-celled microorganisms that often thrive in extreme environments, like hot springs and salty lakes. Archaea are classified into various groups based on their characteristics and habitats, including methanogens (which produce methane), halophiles (salt-loving), and thermophiles (heat-loving). Unlike bacteria, their cell structures and genetic sequences are more similar to eukaryotes, which include plants and animals. This unique classification highlights their distinct evolutionary path and ecological roles in diverse environments.
