  1. Prokaryotes vs Eukaryotes Notes

  2. Objectives/Why does this matter? • Learning Targets: • Are there different types of cells? • How does the endosymbiotic theory explain a eukaryotes nucleus? • Objective: We will be able to use a Venn Diagram in order identify the key characteristics in eukaryotes and prokaryotes.

  3. One way to remember the difference • Prokaryote • Prokaryote has no nucleus • PRO = No or Before • Eukaryote • Eukaryote has true nucleus • EU = True Kary = Nucleus

  4. What are some differences you see between these two cells?

  5. Types of Cells • Prokaryotes • Archaeabacteria • Eubacteria • Eukaryotes (Protists are a clade of eukaryotes that can mimic the three eukaryotic kingdoms) • Animal • Plant • Fungi

  6. What are organelles? • A specialized part of a cell with a specific function  • Mini “organs” of a cell.

  7. cell membrane cytoplasm Bacterium (colored SEM; magnification 8800x) All Cells (prokaryotic and eukaryotic) have • Have DNA (genetic material) • Have Ribosomes • Are enclosed by a Cell membrane. • Are filled with Cytoplasm.

  8. Common features of all cells • Cell Membrane • Outer layer that controls what enters & exits the cell

  9. Common features of all cells 2.Cytoplasm • Jelly like material which cell organelles float in

  10. Common features of all cells 3. DNA- genetic material

  11. Common features of all cells 4. Ribosome – site of protein synthesis

  12. nucleus organelles cell membrane cytoplasm Prokaryotes • Prokaryotic cells • No nucleus • No organelles • Smaller in size • Simple structure • Unicellular

  13. nucleus organelles cell membrane cytoplasm Eukaryotes • Eukaryotic cells • Have a nucleus • Have organelles • Are larger in size • More complex structure • Multicellular

  14. Nucleus • DEFINITION: • Control center of the cell • the “brain” b. FUNCTION: -Stores all DNA Nucleus

  15. Venn Diagram • In your composition book, make a Venn Diagram comparing and contrasting Prokaryotes vs Eukaryotes

  16. Prokaryotes Eukaryotes • Cell Membrane • Cytoplasm • DNA • Ribosomes

  17. Prokaryotes Eukaryotes • No Nucleus • No organelles • Smaller in size • Simple • Unicellular organisms • Cell Membrane • Cytoplasm • DNA • Ribosomes • Nucleus present • Has organelles • Bigger in size • More complex • Multicellular organisms

  18. Prokaryote or Eukaryote???

  23. On the next few slide…. • Practice EOC questions

  24. EOC Practice Question • The diagram shows a drawing of a cell. Which cellular component identifies the cell shown as a eukaryotic cell? EXPLAIN your answer. a. Nucleus b. Ribosome c. Cytoplasm d. Cell membrane

  30. Exit ticket questions (Some have more than one answer) • 1. Which characteristics do all prokaryotic and eukaryotic cells have in common? • A. cell wall B. nucleus C. cell membrane D. organelles E. Ribosome • 2. Which characteristic is NOT common to both prokaryotic and eukaryotic cells? • A. cytoplasm B. reproduction C. nucleus D. cell membrane • 3. In general eukaryotic cells are… • A. smaller than prokaryotic cells B. larger than prokaryotic cells • C. about the same size D. visible to the unaided eye • 4. What is the jelly-like substance in all cells? • A. cell wall B. nucleus C. cytoplasm D. DNA • 5. Which organelle is found in both cell types? • A. nucleus B. cell wall C. ribosomes D. RNA E. DNA F. Cytoplasm
