What is Cell Type?
• Prokaryotic – describes an organism with cells that do NOT have a nucleus
• Eukaryotic – describes an organism with cells that do have a nucleus

What is Cellular Organization?
• Multicellular – organisms are made up of more than one cell
• Unicellular – organisms are made up of one cell

Kingdom Archaebacteria
“extreme bacteria”
• Cell Type – Unicellular
• Cellular Organization – Prokaryotic
• Mode of nutrition –Autotrophic or
Heterotrophic
– Means that some species are autotrophs and some are heterotrophs
Bundren, 2008 9

Kingdom Archaebacteria
Characteristics
• Reproduction – asexual
• Cell Wall – cell walls without peptidoglycan
• Habitat – live in extreme habitats such as hot springs, geysers, volcanic hot pools, brine pools, black smokers, ocean vents
Bundren, 2008 10

Kingdom Archaebacteria
Morning Glory Pool in Yellowstone National Park – note the bright colors from the archaebacteria growing in the extremely hot water.

Kingdom Archaebacteria
12

Kingdom Archaebacteria
• Archaebacteria can live deep in the ocean near geothermal vents called black smokers
• There is no light, so they carry out chemosynthesis instead of photosynthesis
Bundren, 2008 13

Kingdom Eubacteria
• Cell Type – Prokaryotic
• Cellular Organization – Unicellular
• Mode of nutrition – Autotrophic or heterotrophic
• Reproduction – asexual
• Cell Wall – Thick cells walls with peptidoglycan
• Habitat – everywhere!!! (even inside you)
Bundren, 2008 14

Kingdom Eubacteria
• Procholorococcus – an autotrophic bacterium
Bundren, 2008 15

Kingdom Protista: “Catch All Kingdom”
• Cell Type – Eukaryotic
• Cellular Organization – Most unicellular, some multicellular
• Mode of Nutrition – Autotrophic and heterotrophic
• Reproduction – sexual and asexual
• Cell Wall – Some with cell walls containing cellulose
• Habitat – all aquatic
Bundren, 2008 16

Kingdom Protista
Euglena - autotrophic
Volvox – a colonial protist
Bundren, 2008
