Are All Cells Alike

Are All Cells Alike?

• All living things are made up of cells. Some
  organisms are composed of only one cell. Other
  organisms are made up of many cells.
• 1. What are the advantages of a one-celled
  organism?
• 2. What are the advantages of an organism that is
  made up of many cells?

Prokaryote vs. Eukaryote

• Pro- cell with no nucleus nor organelles ie.
  Eubacteria, Archaebacteria
• unicellular (single cell) organisms
• Eukaryote- cell with nuclei and organelles.
• ie. All cells making up organisms of the Domain
  Eukarya. Unicellular and multicellular organisms
