Organelles

  1. 1. LAUNCH <ul><li>Pick two organelles from yesterday, describe their function and draw a quick sketch </li></ul>
  2. 2. LAUNCH <ul><li>What are the differences and similarities between a prokaryotic and eukaryotic cell? What are examples of each? </li></ul>
  3. 3. Parts of the Cell
  4. 4. Plant vs Animal Cells
  5. 6. ANALOGY! Organelles perform the functions of the cell just like different people and places perform the functions of LPS! If the nucleus of a cell is analogous to Ms. Klaffky, the principal, what function do you think the nucleus does?
  6. 7. Control Center Holds genetic material Nucleus
  7. 8. Nucleus Lily Parenchyma Cell. Note the large nucleus and nucleolus in the center of the cell, mitochondria and plastids in the cytoplasm.
  8. 9. Nucleus
  9. 10. <ul><li>Function: Control center of the cell, holds genetic information of DNA </li></ul><ul><li>Found: In all Eukaryotic Cells (both plant and animal cells have nuclei) </li></ul><ul><li>Analogy: Ms. Klaffky (principal) </li></ul>
  10. 11. Power Station Produces Energy Mitochondria Changes chemical energy into food
  11. 12. Mitochondria
  12. 13. Mitochondria
  13. 14. The Cafeteria (MPR) Mitochondria
  14. 15. Mitochondria <ul><li>Function: convert chemical energy stored in food into compounds which cell can use for energy </li></ul><ul><li>Found: In All Eukaryotic Cells in the cytoplasm </li></ul><ul><li>Analogy: Cafeteria </li></ul>
  15. 16. Power Station Produces Energy Chloroplast Changes sunlight into food by photosynthesis
  16. 17. Found in Plants Only Chloroplast
  17. 18. Chloroplast
  18. 19. The Cafeteria (again) Chloroplast
  19. 20. INTRACELLULAR TRANSPORT <ul><li>ER </li></ul><ul><li>Golgi </li></ul><ul><li>Lysosome </li></ul><ul><li>Vacuole </li></ul>
  20. 21. Makes proteins Ribosome Very small
  21. 22. Ribosomes
  22. 23. Ribosome <ul><li>Function: makes proteins; where translation occurs </li></ul><ul><li>Found: In All Eukaryotic Cells; in cytoplasm and on rough endoplasmic reticulum </li></ul><ul><li>Analogy: Guidance Office, Teachers </li></ul>
  23. 24. Pathway to ship proteins Endoplasmic Reticulum
  24. 25. Endoplasmic Reticulum <ul><li>Function: Pathway to ship proteins </li></ul><ul><li>Found: All Eukaryotic Cells in cytoplasm </li></ul><ul><li>Analogy: Hallway </li></ul>
  25. 26. E.R.
  26. 27. E.R.
  27. 28. Hallways Endoplasmic Reticulum
  28. 29. Package and ship out proteins Golgi Apparatus
  29. 31. Golgi Apparatus <ul><li>Function: package and ship out Proteins </li></ul><ul><li>Found: All Eukaryotic Cells in cytoplasm </li></ul><ul><li>Analogy: Ms. Rivera and Ms. Aguilar, Office Secretaries </li></ul>
  30. 32. Golgi Apparatus
  31. 33. Golgi Apparatus
  32. 34. Main Office / Ms. Rivera Golgi Apparatus
  33. 35. Clean up crew Lysosome
  34. 36. Lysosomes <ul><li>Function: cleanup crew of cell – eats old stuff </li></ul><ul><li>Found: All Eukaryotic Cells in cytoplasm </li></ul><ul><li>Analogy: Custodians </li></ul>
  35. 37. The Custodians Lysosome
  36. 38. Lysosome
  37. 39. Exit Ticket! <ul><li>On your index card, write your name and number 1-3 </li></ul><ul><li>For each slide that is shown, write down the ‘mystery organelle’ being described. </li></ul>
  38. 40. <ul><li>Function: Pathway to ship proteins </li></ul><ul><li>Found: All Eukaryotic Cells </li></ul><ul><li>Analogy: Hallway </li></ul>1.
