Classification Carolus Linnaeus 1707 -1778 Father of Taxonomy Gave us the hierarchical system we now use. (with some changes) His system had 3 Kingdoms Animals Plants Minerals Each divided into classes, in turn into orders, families, genus, and species with an additional rank lower than species. © KeslerScience.com
Domain - Archaea Classification Unicellular Prokaryotes – no nuclear membrane Found in extreme environments Salty water Volcanic hot springs Example: Sulfolobus (a microorganism that grows in volcanic springs) Kingdom: Archaebacteria © KeslerScience.com
Domain - Bacteria Classification Found everywhere Prokaryotes – no nuclear membrane Most known and most studied bacteria Example: Streptococcus (the bacteria that causes strep throat) Kingdom: Eubacteria © KeslerScience.com
Domain - Eukarya Classification Kingdom: Found everywhere Most of the world’s living things. Eukaryotes – cell has a nucleus Example: Humans Kingdom: Protista Fungi Animalia Plantae © KeslerScience.com
Kingdom Eubacteria Classification True bacteria Prokaryotic Unicellular Autotrophs and Heterotroph Spherical or rod-shaped Found in soil, rocks, oceans, snow and living organisms © KeslerScience.com
Classification Kingdom Archaeabacteria Differs from other bacteria Prokaryotic Unicellular Autotroph and Heterotroph Found in hydrothermal vents © KeslerScience.com
Kingdom - Protista Classification B Kingdom - Protista Cannot be classified as animal, plant or fungus. Eukaryotes Most are unicellular Autotroph and Heterotroph Ex: slime mold (A), protozoa (B), primitive algae (C) A C © KeslerScience.com
Kingdom - Fungi Classification Multicellular Eukaryotes All heterotrophs – consumers Ex: yeast (A), mushrooms (B), ringworm (C) A B C © KeslerScience.com
Kingdom - Plantae Classification Multicellular Eukaryotes Most live on land Autotrophs – producer, makes its own food Provides food for heterotrophs. © KeslerScience.com
