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
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.
Prokaryotes – Three Shapes: – Cocci – round – Baccilli – rods – Spirilla – spirals Layer of peptidoglycan Classified as gram + or gram – Eubacteria cause most bacterial infections – Strep throat – Lactobacillus (yogurt bacteria)
How Bacteria Get Energy Photosynthesis – energy from sunlight Cellular Respiration – energy from break down of organic material Chemosynthesis – energy from chemicals available in the environment Charts pg. 582-583
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
How Protists Move Pseudopods – “false feet” Cilia – short, numerous, hair-like structures Flagella – relatively long, whip-like; one or two in number
How Protists Obtain Energy Autotrophic – use photosynthesis (green!!!) Heterotrophic – engulf and digest their food
How Protists Impact Humans Parasitic protists cause some of the world’s most deadly diseases – Malaria – African sleeping sickness Many protists are photosynthetic Beneficial in digestion Diatomaceous earth-toothpaste, pool filters, etc.
Autotrophic – make their own food through the process of photosynthesis Cell walls contain cellulose Non-motile Nonvascular – moss Vascular Seedless – ferns Gymnosperms – pine trees Angiosperms – flowering plants
Importance of Plants to the World Primary Producers – the energy source in ecosystems Medicines Removing carbon dioxide from the air and producing oxygen Wood for construction Fibers for clothing
