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
HABITAT! Live in salt water lakes Hot water springs Animal Guts Harsh Environments High temperatures High acids
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
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
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
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.
DIGESTION! Heterotrophs Some photosynthesize of chemical, some break down sulphurs' and some use hydrogen gas
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)
RESPIRATION! CH20 + 02 CO2 + H20 + ATP Anaerobic
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
