  1. skin for cell; seperates cell from environment-
    plasma membrane
  2. condensed; genetic material for DNA for cell-
    chromosome
  3. stringy; genetic material for DNA for cell-
    chromatin
  4. long;move cell or substances across cell surface-
    flagella
  5. short; move cell or substances across cell surface-
    cilia
  6. membrane that encloses nucleus; more porous than cell membrane-
    nuclear envelope
  7. makes ribosmoes (small round bodies in nucleus)-
    nucleolus (nucleoi)
  8. houses DNA that directs cell activities; brain of cell-
    nucleus
  9. storage area for cell; not all cells have these-
    vacuole
  10. communicate & transport within the cell; doesn't have ribosomes attached-

    • rough endoplasmic
    • reticulum
  12. site of protein synthesis or making protein for cell-
    ribosomes
  13. powerhouse of cell; makes ATP-
    mitochondria
  14. digest worn out cell parts or foreign objects-
    lysosomes
  15. packaging center for cell-
    golgi appartus
  16. paired, cylindrical bodies lie at right angles to each other-
    centroiles
  17. small lysosome-like membranous sacs containing oxidase enzymes that detoxify harmful chemicals-
    peroxisomes
  18. cell contents outside nucleus; is major site of most activities carried out by cell (cytosol + organelles)-
    cytoplasm
  19. fluid part of cytoplasm-
    cytosol
  20. minute fingerlike projections that greatly increase the surface area of cell-
    microvilli
  21. nucleus, plasma membrane, cytoplasm-
    3 regions of cells
  22. suspended in the cytosol-
    organelles
