5 Kingdom System
Prokaryotes (Monerans) and 4 eukaryotic kingdoms |
|
|
2 types of prokaryotes
|
Bacteria & archae
|
|
|
Eukaryotic Kingdoms
|
Plants, animals, fungi, protists
|
|
|
Three domains
|
Bacteria, Archae, Eukarya
|
|
|
Three domains differ in types of:
|
rRNA (ribosomal RNA)
tRNA membrane structure antibiotic resistance |
|
|
Eukaryotes
|
"true nucleus"
Have membrane bound nucleus and organelles Contain histone proteins in DNA (linear) May be unicellular or multicellular Have a plasma membrane with sterols May be without a cell wall, may have a cell wall of cellulose, or chitin |
|
|
Prokaryotes
|
"before nucleus"
No membrane bound nucleus or organelles Does not contain histone proteins in DNA Unicellular Plasma membrane does not contain sterols Has a cell wall of peptidoglycan |
|
|
Archaea
|
Lack peptidoglycan (sedomorion)
Unusual methalogy and envrionmental niches Extreme- methanogens, thermophiles,acidophiles |
|
|
Classification of Organisms
|
Domain
Kingdom Phylum Class Order Family Genus Species |
|
|
bacteriology
|
found in bergey's manual of systematic
classifies bacteria according to relationship |
|
|
Thin, gram- cell walls
|
non photosynthetic bacteria, anaerobic photosynthetic bacteria, cyanbacteria
|
|
|
Thick, gram + cell walls
|
rods & cocci
|
|
|
Wall-less eubacteria
|
actinocytes & related mycoplasmas
|
|
|
Unusual Cell Walls
|
Archaea
|
|
|
Classification of Viruses
|
Not in the three domain sysytem
Not composed of cells Use anabolic machinery of host Obligate intracellular parasites Classified according to type of virus (influenza) followed by the strain (H1N1) |
|
|
What Classify's bacteria?
|
Bergey's manual of systematic bacteriology
- Provides determinative schemes - Used to identify unknown |
