2 Archaebacteria vs Eubacteria Characteristics: Unicellular, prokaryotes, autotrophs and heterotrophs Most can’t move Resemble early life formsCharacteristics:Unicellular, prokaryotes, autotrophs and heterotrophsMost are beneficialSome harmful--Strept throat, food poison
3 Archaebacteria vs Eubacteria Habitat:Extreme environments: Acidic,no oxygen, Hot SpringsHabitat:Everywhere EXCEPT extreme areas– skin bacteria
4 Archaebacteria vs Eubacteria Food:Some capture sunlight (photosynthesis), others decaying material Ex. Meat or milkFood:Same as archaebacteria, some use hydrogen or methane (chemosynthesis) Ex. Coal mine methane gas
5 Archaebacteria vs Eubacteria Impact:Responsible for earth’s natural gasImpact:Nature’s recyclers– returns basic chemicals to the environment
6 Archaebacteria vs Eubacteria Cool Facts:Some live inside humansUsed to clean up oil spillsExisted on earth for billions of yearsCool Facts:Turns cucumbers into picklesSome very good to eat-- cheese and yogurtDecomposers--- turn dead organisms into soil
7 Archaebacteria vs Eubacteria Common Features:Both come in various shapes and sizes:RodsSpiralsSpherical
8 Archaebacteria vs Eubacteria Common Features:Some have flagellum (whip) for movement
9 Archaebacteria vs Eubacteria Common Features:Reproduction:1. Asexual: divides into 2 identical cells2. Sexual: 2 parents combine DNA to form new cell3. Conjugation: Transfer DNA throughthread-like structure.
