archaea

A group of prokaryotes whose members differ from bacteria, the most prominent prokaryotes, in certain physical, physiological, and genetic features. The archaea may be aquatic or terrestrial microorganisms. They exhibit a diversity of shapes, including spherical, rodlike, and spiral forms. In addition, archaea can survive in various extreme conditions, including very hot or salty environments. Some archaea require oxygen, whereas others do not. Some produce methane as an end product; others depend on sulfur for their metabolism. The archaea can reproduce by several mechanisms, including binary fission, budding, and fragmentation. While the archaea share some features with bacteria, genetic studies have indicated that archaea are more closely related to eukaryotes than to bacteria.
