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 group discussed?
