Let's Work Together! Characteristics
Archaebacteria belong to a group of primitive prokaryotes that are able to live in an environment that is not suitable for any other living organism. They are found in extreme conditions of acidic, alkaline, salt marshes, and hot sulfur springs. Therefore, they are also called extremophiles, i.e., lover of extreme conditions. They are of different shapes, like spherical, spiral, and rodlike. They are different from bacteria as they have a different cell structure and cell membrane. Unlike bacteria, whose cell walls contain peptidoglycan, the cell walls of archaea do not contain peptidoglycan. Another difference between them is the fact that archaea can survive in conditions where most bacteria cannot. Archaebacteria are divided into three main subgroups, based on the extreme habitats they are found in.
