• Can you name the six major groups of living things on Earth?• How many can you come up with?
•
• Levels of classification• “King Philip Came Over For Grape Soda• Kingdom (bacteria, plants, animals, etc.)• Phylum• Class• Order• Family• Genus• Species
• Idea of Binomeal Nomenclature• All species’ scientific name are Genus species
• Example: Killer Whale• Genus: Orcinus• Species: Orca
• Name: Orcinis orca
• The study of classifying organisms
• Began with Linnaeus
• Involves putting ALL living things into groups showing how closely they are related and how they differ.
• Can be studied by placing species in a diagram, showing how closely related they are• the closer the species branched apart, the more closely related they are
• can make these based on physical traits, or use DNA samples to show how similar they are genetically.
• 6 major kingdoms (currently being changed…)• archaebacteria• eubacteria• protista (being split up)• plantae• animalia• fungi
• archaea-• ancient bacteria, many make energy in strange ways
• eubacteria• bacteria we are more familiar with
ex- strep, e. coli, etc.
• both of these are larger groups than all other groups put together!
• All single-celled, eukaryotic organisms• plant-like (ex. algae)• fungus-like (ex. yeast)• animal-like (many predatory)
• this is mainly what you were growing in your soda bottle succession labs
• Plants-• multi-cellular, photosynthesizing organisms
• have cell wall, large vacuole
• Fungus• multi-cellular, HETEROTROPHIC (must EAT to get their food)
• have cell walls
• ex. athlete’s foot, ringworm, mushrooms
• Animals
• multi-cellular, heterotrophic
• wide range of levels of development
• Sponges – non-mobile in main life phase. Simple group of cells designed to pump water into main cavity and out central opening, acting as filter-feeders
• Cnidarians- (jellies and anemones)- soft, water-filled bodies with stinging cells
• echinoderms (spiny-skinned… ex. sea stars) – 5-parted body, no brain, water skeletal system
• arthropods- (insects) – hard exoskeletons, jointed legs
• mollusks- squid, octopus, snails, bivalves- soft bodies with shells or remnants of a shell
• Worms simple round bodies, some with a simple circulatory system
• amphibians- (frogs salamanders)- slimy bodies, able to breath through skin, have most internal organs that we have
• reptiles- (snakes, lizards)- hard, scaly skin preventing them from drying out
• birds- hollow bones, scales modified to feathers
• Mammalia- mammals- fur, birth to live young, produce milk to feed babies
Which is the least diverse groupdiscussed?
