1 Archaebacteria vs Eubacteria 02/23/2012 pages Know: What roles does bacteria play in human lives?

2 Archaebacteria vs Eubacteria Archaebacteria Characteristics: Unicellular, prokaryotes, autotrophs and heterotrophs Most can’t move Resemble early life forms Eubacteria Characteristics: Unicellular, prokaryotes, autotrophs and heterotrophs Most are beneficial Some harmful--Strept throat, food poison

3 Archaebacteria vs Eubacteria Archaebacteria Habitat: Extreme environments: Acidic,no oxygen, Hot Springs Eubacteria Habitat: Everywhere EXCEPT extreme areas– skin bacteria

4 Archaebacteria vs Eubacteria Archaebacteria Food: Some capture sunlight (photosynthesis), others decaying material Ex. Meat or milk Eubacteria Food: Same as archaebacteria, some use hydrogen or methane (chemosynthesis) Ex. Coal mine methane gas

5 Archaebacteria vs Eubacteria Archaebacteria Impact: Responsible for earth’s natural gas Eubacteria Impact: Nature’s recyclers– returns basic chemicals to the environment

6 Archaebacteria vs Eubacteria Archaebacteria Cool Facts: 1.Some live inside humans 2.Used to clean up oil spills 3.Existed on earth for billions of years Eubacteria Cool Facts: 1.Turns cucumbers into pickles 2.Some very good to eat-- cheese and yogurt 3.Decomposers--- turn dead organisms into soil

7 Archaebacteria vs Eubacteria Common Features: Both come in various shapes and sizes: 1.Rods 2.Spirals 3.Spherical

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 cells 2. Sexual: 2 parents combine DNA to form new cell 3. Conjugation: Transfer DNA through thread-like structure.
