Transcript of "Cell organelle presentation"

  1. 1. Prokaryote Vs. Eukaryote
  2. 2. Big differences <ul><li>Prokaryotes: </li></ul><ul><ul><li>“ Before nucleus” </li></ul></ul><ul><ul><li>Simple, smaller than Eukaryotic cells </li></ul></ul><ul><li>Eukaryotes </li></ul><ul><ul><li>“ True nucleus” </li></ul></ul><ul><ul><li>All Eukaryotes have three basic parts: </li></ul></ul><ul><ul><ul><li>Plasma membrane </li></ul></ul></ul><ul><ul><ul><li>Cytoplasm </li></ul></ul></ul><ul><ul><ul><li>Nucleus </li></ul></ul></ul>
  3. 3. Prokayrotic Cells <ul><li>Kingdoms: </li></ul><ul><ul><li>Archaeobacteria: kingdom of primitive bacteria </li></ul></ul><ul><ul><ul><li>Oldest living organisms on earth </li></ul></ul></ul><ul><ul><li>Eubacteria: true bacteria </li></ul></ul>
  4. 4. Characteristics <ul><li>General characteristics: </li></ul><ul><ul><li>Cell wall: murein </li></ul></ul><ul><ul><ul><li>Penicillin: how it works </li></ul></ul></ul><ul><ul><li>Cell membrane </li></ul></ul><ul><ul><li>Genetic Material </li></ul></ul><ul><ul><ul><li>Naked DNA not enclosed by a membrane </li></ul></ul></ul><ul><ul><li>Prokaryotes are small </li></ul></ul><ul><ul><li>Not able to join into tissue </li></ul></ul><ul><ul><li>Some move using flagellums or cillia </li></ul></ul>
  5. 5. Do NOT have <ul><li>Prokayrotes DO NOT HAVE: </li></ul><ul><ul><li>Nucleus </li></ul></ul><ul><ul><li>Membrane bound organelles </li></ul></ul>
  6. 6. Eukaryotic Cells <ul><li>Larger and more complex than prokaryotes </li></ul><ul><li>Kingdoms: </li></ul><ul><ul><li>Protista, animalia, plantae, </li></ul></ul>
  7. 7. Eukaryotic Cells <ul><li>Evolved from prokaryotic cells </li></ul><ul><li>Contain membrane bound nucleus </li></ul><ul><ul><li>DNA </li></ul></ul><ul><li>Contains specialized organelles “little organs” </li></ul><ul><li>Have the ability to combine into specialized tissue </li></ul>
  8. 8. Essentials <ul><li>Eukaryotic Cells MUST HAVE: </li></ul><ul><ul><li>PLASMA MEMBRANE </li></ul></ul><ul><ul><ul><li>Outer boundary of cell </li></ul></ul></ul><ul><ul><li>CYTOPLASM </li></ul></ul><ul><ul><ul><li>Semi-fluid outside nucleus </li></ul></ul></ul><ul><ul><li>NUCLEUS </li></ul></ul><ul><ul><ul><li>Contains chromosomes </li></ul></ul></ul><ul><ul><ul><li>Separated from cytoplasm </li></ul></ul></ul>
  9. 9. See the difference?
  10. 10. The Origin of Eukaryotic Cells <ul><li>Original Earth atmosphere did not contain oxygen </li></ul><ul><li>Cynobacteria and archaea pumped oxygen into the environment </li></ul><ul><ul><li>Give them a round of applause </li></ul></ul>
  11. 11. <ul><li>Over millions of years oxygen became plentiful and cellular organisms evolved that could survive off of oxygen </li></ul><ul><li>Problem for archaea </li></ul><ul><ul><li>Anaerobic </li></ul></ul>
  12. 12. Solution? <ul><li>Engulf aerobic bacteria into their plasma membrane </li></ul><ul><ul><li>Aerobic </li></ul></ul><ul><li>Some anaerobic bacterium picked up smaller aerobic mitochondrion </li></ul><ul><ul><li>Evolved into mitochondria </li></ul></ul><ul><li>Others happened to pick up photosynthesizing smaller bacteria </li></ul><ul><ul><li>Evolved into chloroplasts </li></ul></ul><ul><li>Now they’re dependent on each other </li></ul>
  13. 13. Supporting evidence <ul><li>Mitochondria are considered proof for this theory </li></ul><ul><ul><li>Contain their own DNA </li></ul></ul><ul><ul><li>Enclosed in their own membrane </li></ul></ul><ul><ul><li>Synthesize their own energy </li></ul></ul>
  14. 14. Resolution <ul><li>Organisms could flourish in new environment </li></ul><ul><ul><li>Further evolution of specialized organelles </li></ul></ul><ul><li>Over millions of years you get infinite types of eukaryotic cells. </li></ul>
  15. 15. What are organelles? <ul><li>Definition: </li></ul><ul><ul><li>specialized structures that perform important cellular functions in eukaryotic cells </li></ul></ul><ul><li>Factory analogy </li></ul><ul><li>Body organ analogy </li></ul>
  16. 17. As a group: <ul><li>For each organelle you will write: </li></ul><ul><li>DEFINITION: short description of what it looks like, where it is found, how to recognize it </li></ul><ul><ul><li>Example: Definition of an iPOD: a small technological device that comes in a variety of colors and contains songs you can play </li></ul></ul><ul><li>The FUNCTION is what it does: its purpose </li></ul><ul><ul><li>Function of an iPOD: used as a portable device to play music and is often used when someone is studying or exercising. </li></ul></ul>
  17. 18. In Small Groups <ul><li>In your small table groups fill out the diagram and DEFINITION AND FUNCTION of all the organelles in a Eukaryotic Cell </li></ul><ul><li>Then: quiz each other on the functions and definitions and the origin of the Eukaryotic cell. </li></ul><ul><li>At the end we will have a face off!! </li></ul>
