Transcript

  • 1. Tour of the Cell 3 2010-2011
  • 2. Cells gotta work to live!
    • What jobs do cells have to do?
      • make proteins
        • proteins control every cell function
      • make energy
        • for daily life
        • for growth
      • make more cells
        • growth
        • repair
        • renewal
  • 3. Making New Cells 2010-2011
  • 4. Cytoskeleton
    • Function
      • structural support
        • maintains shape of cell
        • provides anchorage for organelles
          • protein fibers
            • microfilaments , intermediate filaments , microtubules
      • motility
        • cell locomotion
        • cilia , flagella , etc.
      • regulation
        • organizes structures & activities of cell
  • 5. Cytoskeleton
    • actin
    • microtubule
    • nuclei
  • 6. Centrioles
    • Cell division
      • in animal cells, pair of centrioles organize microtubules
        • spindle fibers
      • guide chromosomes in mitosis
      • Found in an area called the centrosome
  • 7. External Structures
    • Cilia
      • Numerous, short hair-like structures
    • Flagella
      • One or two per cell, long-whip like tail
    • Structure of both are the same!
      • Two single microtubules surrounded by a ring of 9 microtubules.
        • Called a 9+2 arrangement
  • 8.  
  • 9. 2010-2011 Any Questions??
