  1. Made of double layer of phospholiod molecules
    Plasma (cell) membrane
  2. Surrounded by a double layer membrane (nuclear envelope)
    Nucleus
  3. Scattered throughout cytoplasm or bound to Rough ER
    Ribosomes
  4. Double membrane, with inner membrane folds (cristae) enclosing important metabolic enzymes
    Mitochondria
  5. Vesicles containing digestive enzymes
    Lysosome
  6. Network of membranous channels extending throughout the cytoplasm
    ER
  7. Membrane extensions containing microfilaments
    Microvilli
  8. Membranee extensions that contain microtubules
    Cilia
  9. Contains 2 centrioles at right angles
    Centrosomes
  10. Hollow cylinatis of enzymes
    Proteasomes
  11. 6 flattened stacks of membrane
    Golgi Apparatus
  12. What is the difference between active and passive transport?
    • Passive: No cellular energy is required/ high to low
    • Active: Required to move substances from a low to high concentration
  13. Movement of molecules or ions from an area of high concentration to an area of low concentration until equilibrium is reached
    (Passive Transport)
    Diffusion
  14. Molecules combine with special protein carrier molecules that help get them through to the other side
    (Passive Transport)
    Facilated Diffusion
  15. Molecules are forced through a membrane by hydrostatic pressure
    (Passive Transport)
    Filitration
  16. Diffusion of water from an area of high concentration to an area of low concentration
    (Passive Transport)
    Osmosis
