1. Diversity of Life

2. Two Types of Cells Prokaryotic cells Eukaryotic cells
DO NOT have membrane bound organelles
No Nucleus
Unicellular organisms
Eukaryotic cells
Contain membrane bound organelles
Ex: Nucleus, Mitochondria
Make up multicellular organisms

3. Taxonomy
Scientists classify life into groups based on common characteristics and DNA evidence
Use the Linnaean System for Classifiation

4. Linnaean System of Classification

5. Three Domains of Life Largest classification systems Three domains:
Bacteria
Archaea
Eukarya

6. Domain Bacteria
Organisms that don’t contain a nucleus and live under normal conditions

7. Domain Archaea
Organisms that don’t contain a nucleus and live in extreme conditions
Example: Thermophiles, halophiles

8. Domain Eukarya
Organisms that contain a nucleus

9. Kingdoms
