1) Kingdom Archaebacteria consists of 4 main groups:
-Methanogens: Methanogens are important decomposers in marshes and swamps and some of them are important symbionts in termites and other herbivores.
-Halophiles: Halophiles are found in waters of extreme salinity (ranging anywhere from 15 to 20% salinity).
-Thermophiles: Thermophiles are found in mineral springs and thermal volcanic vents on the ocean floor and their habitat is usually hot (60 to 80 degrees celsius).
-Acidophiles: Acidophiles usually stay in acidic environments (pH of 2 to 4), thus their name.
General Information
2) Prokaryotes are very common on earth, they are everywhere. In fact, most bacteria are prokaryotes.
3) Although some people may think that bacterial cell walls and plant cells are similar, they are different. The difference between them is that bacterial cell walls protect the organism while plant cell walls are for mostly structural support.
4) The composition of the cell wall (whether it's gram + or gram -) helps determine what class the bacteria falls under.
5) In the 20th century, scientists discovered gram staining and many other identification factors which helped lead scientists to discovering that molecular systematics showed prokaryotic life to consist of two separate domains (Eubacteria and Archaebacteria).
6) Bacteria are decomposers which break down things like leaves and wood so that their nutrients can be returned to the soil to grow more nutrient dense plants like wood (trees) and leaves.
7) Humans exploit prokaryotes to:
-Recycle nitrogen, carbon, and carbon dioxide.
-Transform food textures.
-Provides more flavor to some foods.
-Produces ethanol
-Provides protection
