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 anddigestive 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

Domain Bacteria- Kingdom Eubacteria

Commoncharacteristics

Mode of Nutrition

Examples

3 Basic Shapes – Cocci(Round), Spirilla (spirals) and Bacilli (Rod shaped)MicroscopicContain 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 oxygenSource of food – yogurt, pickles, cheeses.Breaks down pollutants – bioremediationCause 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 heterotrophFungus-like protists act as decomposers.

Slime molds, algae, diatoms, kelp.

Junk Drawer Kingdom or

Catch All kingdom Most diverse

Protists can be:1. Plant-like2. animal-like3. fungus-like

Reproduction:Sexually Asexually – Algae through fragmentation.

Habitat:Fresh water, oceans, land.

Benefit or harm to humans:Phytoplankton provide oxygenDinoflagellates cause red tide in oceans.May cause diseases like sleeping sicknessFungus-like protists are decomposers.

Red tide caused by dinoflagellates

Domain Eukarya- Kingdom Fungi

Commoncharacteristics

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 – asexuallyThrough binary fission and budding.Multicellular fungi – sexually

Habitat: Soil, air, water

Benefit or harm to humans:Main decomposers.Pathogens cause diseases – athlete’s footFood – 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 seedsSome asexually through stems, leaves, roots.

Habitat: Land

Benefit or harm to humans: Removes CO2 from the air, Produces O2 through photosynthesis.Food source Used to produce clothes, furniture.

Domain Eukarya- Kingdom Animalia

Common characteristics

Mode of Nutrition

Examples

No cell walls ; no chloroplasts, 95% of the kingdom are invertebrates.

heterotrophs

Lions, tigers, bears

Reproduction: Sexually

Habitat: Land, Fresh water, ocean.

Benefit or harm to humans: Insects important for pollination, Some are parasites, Food sourceHumans are also animals!
