Question: Homework: • Can you name the six major groups of living things on Earth? • How many can you come up with?
Introduction to Classification
How We Classify • Levels of classification • “King Philip Came Over For Grape Soda • Kingdom (bacteria, plants, animals, etc.) • Phylum • Class • Order • Family • Genus • Species
Charles Linnaeus • Idea of Binomeal Nomenclature • All species’ scientific name are Genus species • Example: Killer Whale • Genus: Orcinus • Species: Orca • Name: Orcinis orca
Taxonomy • 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.
Another Approach… • 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.
The kingdoms • 6 major kingdoms (currently being changed…) • archaebacteria • eubacteria • protista (being split up) • plantae • animalia • fungi
Bacteria • 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!
Protista • 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
Plantae • Plants- • multi-cellular, photosynthesizing organisms • have cell wall, large vacuole
Fungi- • Fungus • multi-cellular, HETEROTROPHIC (must EAT to get their food) • have cell walls • ex. athlete’s foot, ringworm, mushrooms
Animalia- • Animals • multi-cellular, heterotrophic • wide range of levels of development
Animalia- • 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 bodieswith stinging cells • echinoderms (spiny-skinned… ex. sea stars) – 5-parted body, no brain, water skeletal system • arthropods- (insects) – hard exoskeletons, jointed legs
Animalia- • mollusks- squid, octopus, snails, bivalves- soft bodies with shells or remnants of a shell • Worms simple round bodies, some witha 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
Animalia • Mammalia- mammals- fur, birth to live young, produce milk to feed babies
Question? Which is the least diverse groupdiscussed?
