Kingdom Diversity
3 Domains Domain Archae – contains members of the Kingdom Archaebacteria Domain Bacteria – contain members of the Kingdom Eubacteria Domain Eukarya – Contain members of the Kingdoms Protista, Fungi, Plantae and Animalia
Kingdom Archaebacteria
Archaebacteria Prokaryotes Live in extreme environments Halophiles – salt Thermoacidophiles – heat, acidic environments Methanogens – swamps, intestines of cows No layer of peptidoglycan in cell wall Biochemically more related to eukaryotic cells.
Kingdom Eubacteria
Kingdom Eubacteria Prokaryotes Layer of peptidoglycan Classified as gram + or gram – Eubacteria cause most bacterial infections Strep throat Lactobacillus (yogurt bacteria)
Kingdom Protista
Kingdom Protista Most diverse kingdom’ Eukaryotic Multicellular and unicellular organisms Photosynthetic or heterotrophic Catch all group of eukaryotic organisms that are not animals, plants or fungus Amoebas, paramecium, algae
Kingdom Fungi
Kingdom Fungi Saprotrophic – externally break down food and absorb it, heterotrophic Feed on dead and decaying material Can cause disease – ring worm, yeast infections Cell walls contain chitin (polysaccharide) Mushrooms, truffles, yeast
Kingdom Plantae
Kingdom Plantae Autotrophic – make their own food Cell walls contain cellulose Non-motile Nonvascular – moss Vascular seedless – ferns Gymnosperms – pine trees Angiosperms – flowering plants
Kingdom Animalia
Kingdom Animalia Heterotrophic No cell wall Motile Most recent on the evolutionary time line!
