6 Kingdom EubacteriaBacteria can live in many places on earth, inhabiting a wide variety of habitats, including other organismsUnicellularProkaryoticAutotrophic or heterotrophicThick cells walls with peptidoglycan
7 Kingdom EubacteriaBacteria come in different shapes, such as round, spiral and rod-shaped.
8 Kingdom EubacteriaBacteria can cause a wide variety of diseases, such as strep throat, food poisoning and the Black Death (bubonic plague of the Middle Ages)

10 Kingdom EubacteriaProcholorococcus – an autotrophic bacterium – What does that mean about how it gets its nutrients?
11 Kingdom EubacteriaBacteria from an Nitrifying Trickle Filter (NTF) stained with acridene orange. The stain makes DNA appear yellow and RNA appear orange.

14 Kingdom Archaebacteria Some like it hot! Bacillus infernus
15 Kingdom Archaebacteria Archaebacteria can live deep in the ocean near geothermal vents called black smokersThere is no light, so they carry out chemosynthesis instead of photosynthesis
16 Kingdom Protista Extremely diverse group Eukaryotic Most unicellular, some colonial, some multicellularAutotrophic and heterotrophicSome with cell walls containing cellulose; some carry out photosynthesis with chloroplasts
17 Kingdom Protista Euglena - autotrophic Volvox – a colonial protist A slime moldAmoeba - heterotrophic
18 Kingdom Fungi Eukaryotic Most are multicellular Heterotrophic (decomposers)Cell walls made of chitin
