• methanogens, halophiles, thermacidophiles, and cyanobacteria
  • They live in extreme climates like oceans with lots of salt and hot springs.archaebacteria.gif
  • unicellular
  • prokaryotic
  • The outside of the cell is either gram positive or gram negative which means that antibiotics can or can't pass through the wall. There is no nuclear membrane, cell wall, and no endoplasmic reticulum/
  • Each group of archaebacteria has different ways to get food. Some get it through salt, others make it through photosynthesis.
  • These are the oldest living organisms on earth.


  • E.coli
  • Live everywhere on the earth.
  • Unicellular
  • Prokaryotic
  • Cell wall is made of peptidoglycam. The cytoplasm has a specific structure.
  • photosynthesis, chemosynthesis,decomposing, etc.
  • Eubacteria are the germs that are almost everywhere in our world.


  • Protozoans and algaeprotista.jpg
  • Unicellular but most are multicellular
  • Eukaryotic
  • The cell walls are polymerized or glass like, most have a lot of the same characteristics of plants.
  • Live mostly in water sources
  • A lot of protists feed on bacteria other protists make their own food through photosynthesis
  • Important producer in the food chain


  • Mushrooms and rust
  • Multicellular and unicellularfungi.jpg
  • Eukaryotic
  • Decomposing, from a host (parasite), a consumer
  • Most protists have nucleus that are in the centrioles and have a flagellum.
  • A lot of fungi leave in tropical climates, but the can live almost anywhere.
  • Help to produce antibiotics


  • Trees, grass and bushesplantae.jpg
  • Multicellular
  • Eukaryotic
  • Get food through photosynthesis
  • Plantae have cell walls they help the plant maintain a certain structure.
  • Plants can live anywhere
  • Plants produce oxygen to help people live, we wouldn't be here without them.


  • Humans, platypus, and whales
  • Multicellular
  • Eukaryotic
  • Get food mostly through eating other animas or plants
  • Animals don't have a cell wall because they have to be capable of mobility
  • Animals can live about anywhere on our earth.
  • Animals are an important source of food especially for humans.


  • A virus can not live by itself it must find a living cell.
  • Virus' come in all shapes and sizes and there are many different kinds.
  • Viruses can only make more viruses
  • Bacterial viruses kill harmful bacteria
  • a virus is enclosed in a capsid which keeps all of the genetic material on the inside.
