Classification of Living Things

There are now 6 Kingdoms Archaeabacteria Eubacteria Protista Fungi Plantae Animalia

Domain There are 3 domains: Bacteria Archaea, “ancient bacteria” Eukarya

Domain: Archaea Probably the 1st cells to evolve Live in EXTREME ENVIRONMENTS Ex: thermal vents, volcanic hot springs Unicellular Prokaryotic Cell walls lack peptidoglycan Anaerobic Autotrophs and heterotrophs

Domain: Bacteria Unicellular Prokaryotic Thick, rigid cell walls made of peptidoglycan (purple pigment) Can survive with or without oxygen Heterotrophs and autotrophs Found in ALL HABITATS except harsh ones.

Peptidoglycan

Archaeabacteria vs Eubacteria

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

Protista Most are unicellular, but some can be multi-cellular Eukaryotic Photosynthetic and heterotrophic Examples: Ameoba, protozoan, paramecium

Fungi Heterotrophic Most feed on dead or decaying matter Multicellular and unicellular Examples: Mushrooms, mold, yeasts Cell walls are made of chitin

Plantae Multicellular Photosynthetic autotrophs Non-motile Cell walls contain cellulose Examples: Trees, flowers, bushes, ferns, algae, moss

Animalia Multicellular heterotrophs DO NOT HAVE CELL WALLS Continuous growth throughout life cycle Motile (they can move around) Very DIVERSE kingdom Examples: humans, cats, dogs, fish, worms, snails, lizards

Put it all together

Recap: Cell Structures All cell types EXCEPT ANIMAL have a cell wall Eubacteria: cell wall with peptidoglycan Archaeabacteria: cell wall without peptidoglycan Fungi: cell wall made of chitin Plantae: cell wall made of cellulose Animalia: no cell wall
