Review from Monday! Why is it confusing to refer to an organism by its common name? What is the genus of the grizzly bear if its scientific name is Ursus arctos? If two organisms are in the same family, what other taxonomic groups must they also have in common? Which taxon includes only organisms that can successfully interbreed?

Funny Scientific Names!! Agra vation – Type of beetle Aha ha – Australian Wasp Parastratiosphecomyia stratiosphecomyioides – type of fly, longest scientific name in existence Carmenelectra shechisme (Pronounced “Carmen Electra She Kiss Me) – type of moth

Six Kingdom System The six kingdoms are: Plantae Animalia Fungi Protista Eubacteria Archaebacteria

The Six Kingdom System: Archaebacteria Include prokaryotes without membrane bound nuclei Live in extreme environments without Oxygen Microscopic Unicellular Cell Walls Autotrophs or Heterotrophs Oldest fossils are 3.5 Billion years old

The Six Kingdom System: Eubacteria Are prokaryotes that have very strong cell walls Microscopic Unicellular Heterotrophs & Autotrophs Live in most habitats except extremes where archaebacteria live. Some cause disease, most are harmless and/or helpful. Archaebacteria and eubacteria together are called monera and make up the most amount of biodiversity in the world.

Bacteria are the most common form of life – there are about 30 nonillion of them! That’s this many: 3,000,000,000,000,000,000,000,000,000,000 There are more bacteria in your digestive system then there are on the earth!

The Six Kingdom System: Protista Eukaryotic Means “very first” meaning they were the first eukaryotes Lacks complex organ systems 10,000 known species Lives in moist environments Oldest fossils are 2 billion years old Unicellular & Multicellular Can be plant-like autotrophs, animal-like heterotrophs, or fungus-like heterotrophs. Very diverse kingdom, a hodgepodge of eukaroytic organisms that did not fit into the other eukaryotic kingdoms.

The Six Kingdom System: Fungi Eukaryotic Unicellular & Multicellular Heterotrophs only! Does not move place to place Absorbs nutrients from organic materials in the environment Oldest fossils are 400 million years old 100,000 known species

The Six Kingdom System: Plantae Multicellular only! Autotrophs, Photosynthetic Eukaryotes Do not move place to place Contain Chloroplasts & Cell Walls made of Cellulose. Oldest fossils are 400 million years old. 500,000 known species Have organized tissues that make up organs and organ systems.

The Six Kingdom System: Animalia Multicellular only! Heterotrophs Carnivores : meat only Herbivores : plants only Omnivores : meat and plants Eukaryotes Able to move place to place Oldest fossils are 600 million years old. 1.5 Million known species (maybe 20x that number unknown) 100 species go extinct everyday 40,000 go extinct per year since 2000, the highest in 65 million years! 200 animal species are endangered in the USA. 1000 endangered worldwide.

How do we Classify Organisms? We can create dichotomous keys – a set of paired statements that describe physical characteristics of different organisms.

Classification Puzzle You will work in groups to fill in a table on domains, the 6 kingdoms, and classification. The table will have lots of missing spaces and you will use the clues from the parts of the table that are filled in to figure out what goes in the blanks. When you finish working as a group, you can copy the answers onto your own worksheet.
