Answer 2

• Archaebacteria are special since they live in some of the most hard habitats like extreme salty areas, hot spring and marshy areas.
• They are most primitive prokaryotes.
• They are found in stressed environment conditions like high salt content, edge of ocean, hot sulphur spring, volcanic walls, gut of animals, etc.
• Their cell wall lack peptidoglycan.
• In most cases the cell wall is composed of non cellulosic polysaccharides and some proteins.
• In some members cell walls may even be absent.
• This feature of having different kinds of cell walls is responsible for their survival in extreme conditions.
• Most of them are chemoautotrophic.
• There are three kinds of archaebacteria - Methanogens, Halophiles and Thermoacidophiles.
