Classification- Organisms grouped by shared characteristics and relationships
Levels of Classification Domain Kingdom Phylum Class Order Family Genus Species
Mnemonic: Does King Philip’s Chef Only Fix Green Salads?
Mnemonic: Don’t Knock People Clean Out For Getting Smart
Taxonomy Science of identifying, naming, and classifying organisms Carolus Linnaeus- classified by shared traits
Modern Classification Presumed evolutionary relationships Common ancient ancestors (See p. 86) Branching Diagrams to illustrate

Kingdoms and Domains Plant or Animal? Only 2 kingdoms for long time WHY have more kingdoms been added?
Domains 1. Archae- single celled, can live in extreme or moderate environments 2. Bacteria – (Prokaryotic – no nucleus) Found anywhere! Can be good or bad. 3. Eukarya– (Have Nucleus) All the Kingdoms fit in this Domain!
Domain: Bacteria
Eureka! Euglena? Green, photosynthesis - plant? But, moves with flagella & can eat when chloroplasts don’t get sun- animal?
New Kingdom Protista
Protista
Kingdoms in Eukarya Protista- Protozoans: animal like, or algae: plant like. Also includes slime molds and euglenoids. Fungi- Do not eat food, do not perform photosynthesis. Absorb nutrients from surroundings.
Kindgoms in Eukarya Plantae- eukaryotic, cell walls, perform photosynthesis to obtain energy. Animalia- complex, multi cellular, can find and eat their own food, often rely on other kingdoms such as plants.
Fungus
Plantae
Animalia
