Archaebacteria
By: Morgan, Kayla and Majid

2. SAMPLE ORGANISMS! Methogens which produce methane gas
Extreme thermophiles that thrive in temperatures up too 110 degrees celsius
Extreme Halophiles which are organisms that live in very salty water

3. HABITAT! Live in salt water lakes Hot water springs Animal Guts
Harsh Environments
High temperatures
High acids

4. CHARACTERISTICS AND CLASSIFICATION!
Archaebacteria often life in environments where most other organisms cannot survive distinguishing themselves from others
Classified as a phylum
The cells contain a thick cytoplasm that contains all of the molecules and compounds of metabolism and nutrition

5. CORPORAL STRUCTURE! Prokaryote
Cell membrane is a branched chain with linked lipids
Archae cells only contain a limited amount of organelles
Unicellular (single celled)
Lack complex organ systems
Radial symmetrical (cutting through central axis at any point produces two halves that are mirror images)
Move by flagella

6. REPRODUCTION AND LIFE CYCLE!
Reproduce asexually by binary fission
Their abundance is largely a result of their rapid rate of reproduction
During the process of conjugation, genetic material is exchanged between 2 bacteria. Lead to genetic recombination causing that continued evolution of Archaebacteria

7. CIRCULATION!
Archaebacteria don’t have a heart therefore no circulation whatsoever
Some use diffusion across the cell membrane to get the necessary gases for life in the cell.

8. DIGESTION! Heterotrophs
Some photosynthesize of chemical, some break down sulphurs' and some use hydrogen gas

9. NERVOUS SYSTEM! Archaebacteria do not have brain
They do have a nervous system
Respond to light (phototaxis), food (chemotaxis), temperature (thermotaxis) and to each other (conjugation)

10. RESPIRATION!
CH  CO2 + H20 + ATP
Anaerobic

11. INTERESTING FACTS!
Archaebacteria were one of the first life forms to evolve on Earth!
Archaea are interesting organisms in that they have genes that are similar to both bacteria and eukaryotes!
No species of Archaebacteria is known to cause infection or disease
