question: homework:

• 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?
