Domain Archaea - Kingdom Archaebacteria Common characteristics Mode of Nutrition Examples Cell wall with NO peptidoglycan, microscopic Autotroph or heterotroph Live in extreme environments (extremophiles) such as Halococcus which lives in extremely salty water like the Dead Sea, Methanogens.
Reproduction: Asexual (Binary fission) ‘Sexual’ through conjugation. Habitat: Harsh, extreme environments such As salt lakes, hot springs (Thermophiles), thermal vents, arctic waters and digestive tract of animals (Methanogens) Harm or use to humans: Those living in the digestive tract of animals help with digestion.
Found in hot thermal vents deep under the ocean. Bacteria ‘strain 121’ found in 2003 – ‘hottest’ bacteria to date. Live in water temperatures of up to 121C Hot springs in Yellow Stone National Park Archaebacteria contribute to the bright colors.
Domain Bacteria - Kingdom Eubacteria Common characteristics Mode of Nutrition Examples 3 Basic Shapes – Cocci(Round), Spirilla (spirals) and Bacilli (Rod shaped) Microscopic Contain peptidoglycan in their cell walls. Autotroph (Cyanobacteria) or heterotroph (called pathogens – cause illness E. coli; Salmonella, Streptococci
Reproduction: Asexual (Binary fission) ‘Sexual’ – Conjugation – exchange genetic material. Habitat: Anywhere – water, soil, roots of plants, inside living cells. Benefit or harm to humans: Cyanobacteria produces oxygen Source of food – yogurt, pickles, cheeses. Breaks down pollutants – bioremediation Cause disease – Salmonella, E. coli
Domain Eukarya - Kingdom Protista Common characteristics Mode of Nutrition Examples Microscopic to very large organisms, plant-like, fungus- like and animal-like species. Animal-like move with cilia, flagella and pseudopodia. Autotroph or heterotroph Fungus-like protists act as decomposers. Slime molds, algae, diatoms, kelp. Junk Drawer Kingdom or Catch All kingdom Most diverse
Protists can be: 1.Plant-like 2.animal-like 3.fungus-like
Reproduction: Sexually Asexually – Algae through fragmentation. Habitat: Fresh water, oceans, land. Benefit or harm to humans: Phytoplankton provide oxygen Dinoflagellates cause red tide in oceans. May cause diseases like sleeping sickness Fungus-like protists are decomposers.
Domain Eukarya - Kingdom Fungi Common characteristics Mode of Nutrition Examples cell walls w/ chitin (no chloroplasts), No roots, stems or leaves. Heterotroph,absorption, Some parasitic, other decompose dead matter (saprophytic) Mushrooms, mold, mildew, yeast (unicellular)
Reproduction: Unicellular fungi – asexually Through binary fission and budding. Multicellular fungi – sexually Habitat: Soil, air, water Benefit or harm to humans: Main decomposers. Pathogens cause diseases – athlete’s foot Food – mushrooms, yeast to bake bread with.
Domain Eukarya - Kingdom Plantae Common characteristics Mode of Nutrition Examples cell walls w/ cellulose, chloroplasts, Have stems, leaves, roots. Some have seeds and vascular systems. autotrophs Grass, pine trees, oak trees,etc.
Reproduction: Mainly sexually – pollen and seeds Some asexually through stems, leaves, roots. Habitat: Land Benefit or harm to humans: Removes CO 2 from the air, Produces O 2 through photosynthesis. Food source Used to produce clothes, furniture.
