  2. * Cell type * • Archaebacteria is a prokaryotic.

  3. * CELL WALL * • Archaebacteria have a cell wall that contains no peptidoglycan. This rigid cell wall supports the cell, allowing an archaebacterium to maintain its shape, and protecting the cell from bursting when in a hypotonic environment. Because these organisms have no nucleus, the genetic material floats freely in the cytoplasm.

  4. * Number of cells * • Archaebacteria have one cell. They are unicellular prokaryotes.

  5. * Nutrition * • Archaebacteria are described as being obligate anaerobes; that is, they can only live in areas without oxygen. Autotrophy is the ability to be self-sustained by producing food from inorganic compounds.

  6. * Reproduction * • Archaebacteria are asexual organism that reproduce either by fragmentation, budding of binary fusion (splitting in two).

  7. * Effect Environment * • Archaebacteria might be harmful to humans because of its ability to survive the human body, weaken its immune system, and cause disease. Though, there are still no studies or diseases that linked this type of bacteria to human.

  8. * Interesting Fact * • It is widely believed that archaebacteria are approximately 3.5 billion years old, and have been on planet Earth for almost as long as it has existed. Compare this 3.5 billion years with the 600 million years for which animals have existed, and animals, including human beings, are practically babies! Because of their age, archaebacteria are more useful than most bacteria for research into evolution and the origin of life

  9. * Examples * • Methanogens : The methanogens are archaeans that produces methane gas or biogas. Methanogens are anaerobes or bacteria that do not need oxygen in order to live.Methanogens living in swamps are responsible for bubble formations or the so-called marsh, or swamp, gas.
