  2. the region between the nucleus and plasma membrane is the

  3. only plant cells have
    only animal cells have
    • chloroplasts
    • lysosomes
  4. phospholipids have
    • a negatively charged head
    • two nonpolar fatty acid tails
  5. fluid mosaic
    fluid because molecules can move freely past one another
  6. plant cell walls are made of

  8. the components of ribosomes are made in the
    nucleoulus
  9. the endomembrane system in a cell consists of
    • the nuclear envelope
    • endoplasmic reticulum
    • the golgi apparatus
    • lysosomes
    • vacuoles
  10. purpose of golgi apparatus
    receives, refines, stores, and distributes chemical products of the cell
  11. lysosome is a
    membrane enclosed sac of digestive enzymes found in animal cells
  12. vacuoles
    are large sacs made of membrane that bud of from ER or golgi apparatus
  13. mitochondria
    produces atp from the energy of food molecules
