Presentation Transcript

  1. Fluid Mosaic Model

  2. Phospholipid molecule

  3. Passive Transport - requires NO cell energy

  4. Passive Transport: (a) Simple Diffusion molecules move from high to low between phospholipid molecules

  5. molecules move from high to low with the help of plasma proteins (b) Facilitated diffusion

  6. Ion Channel • Ions have charges (positive or negative) and will not pass through the lipid bilayer which has a nonpolar interior.

  7. requires cell energy molecules move from low to high molecules move against the gradient Active Transport

  8. a) Solute Pump

  9. b) Bulk Transport (a) exocytosis

  10. (b) endocytosis

  11. Concept Map

  12. the repeating events in the life of a cell Includes: 1) Interphase 2) Mitosis 3) Cytokinesis Cell Cycle

  13. Normal cell activity (the time between cell divisions) Growth of cell (G phase) At the end, DNA replicates Interphase

  14. www.kensbiorefs.com/cellstructure.html Mitosis

  15. division of the cytoplasm animal cells form a cleavage furrow cytokinesis
