Transcript

  • 1. Cells and their Organelles
  • 2. Two Types of Cell Prokaryote Eukaryote
    • No membrane bound organelles
    • Flagellum
    • Gel-capsule on outside
    • bacteria
    • Has membrane bound organelles
    • DNA is contained in nucleus
    • All plant and animal cells
  • 3. Two types of Eukaryotic Cell Animal Plant Cytoplasm Cytoskeleton Cell membrane Nucleus Nucleolus Mitochondria Ribosomes Endoplasmic Reticulum Golgi Bodies
    • Large Central Vacuole
    • Chloroplasts
    • Cell Wall
  • 4. Animal Cell Diagrams
  • 5. Plant Cell Diagrams
  • 6. Cell Membrane
    • Outer covering of the cell
  • 7. Cell Wall
    • Rigid outer covering of a plant cell that protects the cell and gives it shape
  • 8. Cytoplasm
    • Gel-like substance that the organelles float around in
    • Contains the cytoskeleton which gives structure to the cell
  • 9. Nucleus
    • Command and control center of the cell
    • Contains the DNA
    • Surrounded by the Nuclear membrane
  • 10. Nucleolus
    • Is inside the nucleus
    • Ribosome's are made here
  • 11. Mitochondria
    • Powerhouse of the cell
    • Makes ATP which gives the cell energy
  • 12. Chloroplasts
    • Contain chlorophyll the green pigment that makes photosynthesis possible
    • Makes glucose = sugar = plant food
  • 13. Ribosome
    • Makes RNA chains which then make proteins
    • Can be free floating or attached to the endoplasmic reticulum
    • They look like dots in the cell
  • 14. Endoplasmic Reticulum
    • AKA the ER
    • Can be smooth or rough
      • Rough has ribosomes attached to it
    • Makes and transports proteins
  • 15. Golgi Bodies or Apparatus
    • Sort and package proteins and other substances to deliver to the rest of the cell or outside the cell
    • The “packages” that move the materials are called vesicles
  • 16. Vacuole
    • Hold food and water for the cell
    • Plant cells have a large central vacuole
    • Animal cells have small vacuoles
  • 17. Cell Misconceptions
    • The larger the organism doesn’t = larger cells
    • All the cells in your body have the EXACT same organelles, they just look different!
  • 18. Different cells in the body
