EVERYDAY SCIENCE

Detailed explanation-1: -Archaea consists of three RNA whereas bacteria consists of single RNA. Archaea can sustain in harsh environments which are extreme such as hot springs, oceans, gut of humans and Marshlands. Bacterias are generally found in organic matter, soil, bodies of animals and plants, water, radioactive waste, etc.

Detailed explanation-2: -Scientists had known that this group of microbes – called archaea – were surrounded by a membrane made of different chemical components than those of bacteria, plants or animals. They had long hypothesized that it could be what provides protection in extreme habitats.

Detailed explanation-3: -Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.

Detailed explanation-4: -Archaea is the main group to thrive in extreme environments. Although members of this group are generally less versatile than bacteria and eukaryotes, they are generally quite skilled in adapting to different extreme conditions, holding frequently extremophily records.

Detailed explanation-5: -Archaea that live in extremely hot environments are called thermophiles. Archaea that produce methane are called methanogens. Archaea are known for living in extreme environments, but they also can be found in common environments, like soil.
