How are living things organized? Diversity and Classification

CLASSIFICATION Taxonomy

Binomial Nomenclature System of how organisms are named by using two titles Universal system Sometimes in different languages First word: Genus Second word: species Prevents confusion when talking about different organisms

How To Remember This: Keep = Kingdom Pond = Phylum Clean = Class Or = Order Froggy = Family Gets = Genus Sick = species

Phylogeny The study of the evolutionary history of an organism(s)

Molecular Clocks a technique that uses the amino acid sequence of an organism to determine the time frame

Domain Classifications Bacteria Archaea Eukarya

Domain Bacteria Kingdom Eubacteria Unicellular and prokaryotic with peptidoglycan

Domain Classifications Bacteria Archaea Eukarya

Domain Archaea Single celled prokaryotes These cells do not contain peptidoglycan

Domain Classifications Bacteria Archaea Eukarya

Domain Eukarya includes the kingdoms Protista, Fungi, Plantae, and Animalia

Protists vs. Fungi

Protists Both multi-cellular and unicellular Can be animal-like, plant-like, or fungi-like All protists are eukaryotes (DNA is found in a nucleus) ex=6&list=PLH_k9U2J8_hyXrEky9_Kv0FS74coWq7 _9 ex=6&list=PLH_k9U2J8_hyXrEky9_Kv0FS74coWq7 _9

Protists vs. Fungi

Fungi Includes unicellular organisms (like yeasts and molds) and multicellular organisms (such as mushrooms) st=PLH_k9U2J8_hyXrEky9_Kv0FS74coWq7_9&ind ex=5 st=PLH_k9U2J8_hyXrEky9_Kv0FS74coWq7_9&ind ex=5
