Aug. 24(plant vs. animal cells)

  1. 1. Biology I Mr. Nettles
  2. 2. Agenda- Wednesday, August 24, 2011 <ul><li>Warm Up – 5 min </li></ul><ul><li>Review Activity – 10 min </li></ul><ul><li>Daily Lesson – 20 min </li></ul><ul><li>Wrap Up (in teams) – 10 min </li></ul><ul><li>Begin Homework – 15 min </li></ul>
  3. 3. Today’s Objectives <ul><li>I will define the words: vacuole, cell wall, chloroplast, and centriole. </li></ul><ul><li>I will define and describe the primary organelles of eukaryotic cells. </li></ul><ul><li>I will articulate the differences between plant and animal cells. </li></ul>
  4. 4. Warm-Up <ul><li>Define organelle. </li></ul><ul><li>Identify two differences between the ER and the Golgi apparatus. </li></ul><ul><li>Which organelle is responsible for breaking down dying organelles and food particles within cells? </li></ul>
  5. 5. Review : Come up with a school-related analogy for the different parts of the cell <ul><li>Nucleus - Central Office </li></ul><ul><li>Nucleolus - Guidance Office </li></ul><ul><li>Cytoplasm - ? </li></ul><ul><li>Cell membrane - ? </li></ul><ul><li>Ribosome - ? </li></ul><ul><li>Endoplasmic Reticulum - ? </li></ul><ul><li>Golgi apparatus - ? </li></ul><ul><li>Mitochondria - ? </li></ul><ul><li>Lysosomes - ? </li></ul>
  6. 6. Plant Cells vs. Animal Cells
  7. 7. Vacuoles (what they both have) <ul><li>Definition : </li></ul><ul><ul><li>fluid-filled sac </li></ul></ul><ul><ul><ul><li>Small in animal cells </li></ul></ul></ul><ul><ul><ul><li>Large in plant cells </li></ul></ul></ul><ul><li>Function : </li></ul><ul><ul><li>Used to store materials needed by the cell like water, food and enzymes </li></ul></ul><ul><ul><ul><li>Supports heavy structures like leaves and flowers in plants </li></ul></ul></ul>
  8. 8. Organelles found ONLY in Plants: Cell Walls Chloroplasts
  9. 9. Cell Wall <ul><li>Definition : </li></ul><ul><ul><li>A rigid layer that surrounds the cell membrane </li></ul></ul><ul><li>Function : </li></ul><ul><ul><li>To provide support and protection for the cell </li></ul></ul><ul><ul><ul><li>The cell walls of multiple cells can attach to one another to support the organism </li></ul></ul></ul><ul><ul><ul><li>Cell walls are made of different materials depending on the organism </li></ul></ul></ul><ul><li>*Note: Cell walls are also found in prokaryotic cells . </li></ul>
  10. 10. Cell wall
  11. 11. Chloroplasts <ul><li>Definition: </li></ul><ul><ul><li>Are organelles that have a double membrane and stacks of disc-like shapes containing chlorophyll </li></ul></ul><ul><li>Function : </li></ul><ul><ul><li>Use energy from the sunlight to make food for the cell through the process of photosynthesis </li></ul></ul><ul><ul><ul><li>Chlorophyll gives plants their green color </li></ul></ul></ul><ul><ul><ul><li>Like mitochondria because it provides energy </li></ul></ul></ul>
  12. 12. Chloroplast
  13. 13. PLANT CELL Cell wall Large vacuole Chloroplast
  14. 14. Organelle found ONLY in Animals: Centrioles
  15. 15. Centrioles <ul><li>Definition: </li></ul><ul><ul><li>Are barrel-shaped organelles composed mostly of microtubules </li></ul></ul><ul><li>Function : </li></ul><ul><ul><li>Organize and transfer chromosomes and other organelles during Meiosis and Mitosis </li></ul></ul><ul><ul><li>Serve as the construction point for cellular microtubules </li></ul></ul><ul><li>*Note: Centrioles are also found in some prokaryotic cells . </li></ul>
  16. 16. Centriole
  17. 17. Small vacuole Centriole
  18. 18. Wrap-Up <ul><li>Get in teams of two or three people. </li></ul><ul><li>Take out a sheet of paper to write your answers. </li></ul><ul><li>In the questions that follow, your team needs to “Name that Organelle”. </li></ul>
  19. 19. Question 1 <ul><li>I’m a real “powerhouse” </li></ul><ul><li>That’s plain to see </li></ul><ul><li>I break down food </li></ul><ul><li>To release energy </li></ul><ul><li>What am I? ______________________ </li></ul>
  20. 20. Question 2 <ul><li>I’m strong and stiff </li></ul><ul><li>Getting through me is tough </li></ul><ul><li>I’m found only in plants </li></ul><ul><li>But I guess that’s enough </li></ul><ul><li>What am I? _____________________ </li></ul>
  21. 21. Question 3 <ul><li>I’m the brain of the cell </li></ul><ul><li>Or so they say </li></ul><ul><li>I regulate cell activities </li></ul><ul><li>From day to day </li></ul><ul><li>What am I? ____________________ </li></ul>
  22. 22. Question 4 <ul><li>Found only in plant cells, </li></ul><ul><li>I’m green as can be </li></ul><ul><li>I make food for the plant </li></ul><ul><li>Using the sun’s energy </li></ul><ul><li>What am I? ______________________ </li></ul>
  23. 23. Question 5 <ul><li>I’m a series of tubes </li></ul><ul><li>Found throughout the cell </li></ul><ul><li>I transport proteins </li></ul><ul><li>And other things as well </li></ul><ul><li>What am I? ___________________ </li></ul>
  24. 24. Question 6 <ul><li>I’m full of holes </li></ul><ul><li>Flexible and thin </li></ul><ul><li>I control what gets out </li></ul><ul><li>And what comes in </li></ul><ul><li>What am I? _________________ </li></ul>
  25. 25. Question 7 <ul><li>Proteins are made here </li></ul><ul><li>Even though I’m quite small </li></ul><ul><li>You can find me in the cytoplasm </li></ul><ul><li>Or attached to E.R.’s wall </li></ul><ul><li>What am I? ______________________ </li></ul>
  26. 26. Question 8 <ul><li>I’ve been called a “storage tank” </li></ul><ul><li>By those with little taste </li></ul><ul><li>I’m a sac filled with water </li></ul><ul><li>Food, enzymes, or waste </li></ul><ul><li>What am I? ______________________ </li></ul>
  27. 27. Question 9 <ul><li>Since I contain many enzymes, </li></ul><ul><li>I can digest an injured cell; </li></ul><ul><li>And can break down a large molecule </li></ul><ul><li>Into a smaller one as well </li></ul><ul><li>What am I? ______________________ </li></ul>
