Presentation Transcript

  1. Cell Organelles

  2. Review • No organelles in prokaryotic cells • Both plants and animals are eukaryotic cells!

  3. Animal Cell

  4. Plant Cell

  5. Organelles Found in Plant and Animal Cells • Cell Membrane • Nucleus • Nucleolus • Mitochondria • Endoplasmic reticulum • Ribosomes • Golgi apparatus • Vacuoles (small in animals; large in plants) • Lysosomes

  6. The Cell Membrane • Location: Around the outside of the cell • Function: Controls what substances enter and leave the cell • Aka: “plasma membrane”

  7. Nucleus • Location: In the cytoplasm • Function: Directs all of the cell’s activities; stores the chromatin • Aka: “control center”

  8. Nucleolus • Location: In the nucleus • Function: Makes ribosomes • Aka: “little nucleus”

  9. Mitochondria • Location: In the cytoplasm • Function: Produces energy • Aka: “Powerhouse” or “Mighty Mitochondria”

  10. Ribosomes • Location: In the cytoplasm and on the rough ER • Function: Makes protein • Aka: “Protein packs”

  11. Endoplasmic Reticulum (ER) • Location: In the cytoplasm around the nucleus • Function: Modifies materials needed in the cell • Aka: “Fashion designers” Smooth ER (no ribosomes) Rough ER (has ribosomes)

  12. Golgi Apparatus • Location: In the cytoplasm • Function: Sorts and ships materials to the correct parts of the cell • Aka: “the post office”

  13. Vacuoles • Location: In the cytoplasm (large in plants; small in animals) • Function: Storage • Aka: “the closet” Animal Cell Vaculole = small Plant Cell Vaculole = large

  14. Lysosome • Location: In the cytoplasm • Function: Destroys worn out cell parts • Aka: “the death chamber:

  15. Cilia / Flagella • (*animal cells only: not all cells have one of these) • Location: on the cell membrane • Function: help the cell move

  16. Organelles Found in Only Plant Cells • Cell Wall • Chloroplast

  17. Cell Wall • Location: Around the cell membrane of plant cells • Function: Gives the cell shape and protection • Aka: “plant cell armor”

  18. Chloroplast • Location: In the cytoplasm • Function: Photosynthesis: Makes sugar from sunlight (also takes in carbon dioxide and gives off oxygen) • Aka: “mean green sugar machine”

  19. See the Cell in Action! • Visit this link to see the cell in action, just click on the various organelles to get a better idea of how they work! http://www.johnkyrk.com/CellIndex.html • And, check out Cells Alive! http://www.cellsalive.com/cells/cell_model.htm
