  1. WK 1.08 Cells: Prokaryotes

  2. REMINDER: Cell Theory • All living organisms are composed of cells. They may be unicellular or multicellular. • The cell is the basic unit of life. • Cells arise from pre-existing cells.

  3. 2 Main Kinds • When we look at types of cells, we break them down into two main categories: • Prokaryotes • “simple” • “circular DNA” • Cell wall • Eukaryotes • Complex • Have “organelles”

  4. Eukarotes(Plant, Fungi, Animal) http://micro.magnet.fsu.edu/cells/

  5. Prokaryotes • Is it THAT simple?. • Photo: wiki

  6. Prokaryotes • YES!

  7. Bacterial shapes • Staphylococcus bacteria • Bacillus • Spirillum • Photo: wiki

  8. REMEMBER • Prokaryotes DO NOT have a nucleus, mitochondria, or any other membrane-bound organelles. They DO have a cell wall. • Photo: wiki
