#Archea #domainarchea #howarcheaareunique #archeacharactersandreproduction [18/10, 11:24 pm] Meta AI: Domain Archaea comprises single-celled prokaryotes distinct from bacteria and eukaryotes. Key traits: *Cell wall*: lacks peptidoglycan (often pseudo‑peptidoglycan or S‑layers). *Membrane lipids*: ether‑linked isoprenoid chains, forming monolayers or bilayers. *Genetics*: introns, histone‑like proteins, and transcription/translation machinery resembling eukaryotes. *Metabolism*: diverse, including methanogenesis, sulfur reduction, and chemolithoautotrophy; many are extremophiles (halophiles, thermophiles, acidophiles). *Phylogeny*: major phyla include Euryarchaeota, Crenarchaeota, Nanoarchaeota, Asgard archaea (e.g., Lokiarchaeota). These features position Archaea as a unique evolutionary lineage bridging bacteria and eukaryotes. [18/10, 11:24 pm] Meta AI: Domain Archaea 😊. These are single-celled microorganisms that are prokaryotic, meaning they lack a true nucleus and other membrane-bound organelles. Archaea are known for their ability to thrive in extreme environments like hot springs, salt lakes, and acidic environments. They play important roles in ecosystems and have unique metabolic processes 🍂.
