A group of microorganisms that look like bacteria but have different cell structures. They are sometimes considered a separate kingdom and sometimes considered a division of the prokaryotes.
These microorganisms are called Archaea. They are known for their ability to thrive in extreme environments such as hot springs, deep-sea vents, and salt flats. Unlike bacteria, Archaea have unique lipid membranes and different cell wall components. They also have a distinct genetic makeup and metabolic processes. Despite being often mistaken for bacteria, archaea are evolutionarily distinct and have a unique place in the tree of life.
