6. The evolutionary history of a group of species Phylogeny .

8. A cladogram is a tree that proposes how species are related through common ancestry.

9. 1) Bacteria 2) Archaea 3) Eukarya
Domain is a level of classification that is higher than Kingdom.
There are three domains.
1) Bacteria
2) Archaea
3) Eukarya

10. Bacteria : singled-celled prokaryotes that are not extremophiles.

11. Archaea : singled-celled prokaryotes that are extremophiles
Archaea : singled-celled prokaryotes that are extremophiles. Their cell walls are different from bacteria. An extremophile is an organism that LOVES (philo) extreme conditions.

12. Mr. Allen, what is a eukaryotic cell?
Eukarya : ALL organisms with eukaryotic cells.
Mr. Allen, what is a eukaryotic cell?

13. The domain Eukarya includes the kingdoms 1) Animalia 2) Plantae 3) Fungi 4) Protista

15. Animals – multicellular and heterotrophic.

16. Plants – multicellular and autotrophic.

17. Protists – unicellular. Can be heterotrophic or autotrophic.

18. Fungi – unicellular and multicellular. They are saprophytic
Fungi – unicellular and multicellular. They are saprophytic. NOT photosynthetic. Saprophytic means that it obtains nutrients from dead organic matter.

19. Important Animal Phyla Chordates – all animals with a backbone
Important Animal Phyla Chordates – all animals with a backbone. Mammals, Reptiles, Birds, Amphibians, and others… Arthropods – animals with many joints. Insects, Arachnids, Crustaceans (crabs) Mollusks – soft body animals (sometimes with shells). Snails, cephalopods, clams, slugs…
