1. Classification of Living Things

2. There are now 6 Kingdoms Archaeabacteria Eubacteria Protista Fungi
Plantae
Animalia

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

5. 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

6. 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.

7. Peptidoglycan

8. Archaeabacteria vs Eubacteria

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

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

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

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

13. 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

14. Put it all together

15. 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
