  1. Nucleus

    Function

    Why is the nucleus reffered to as the main office?
    holds hereditary information

    Sends information in/out
  2. Cytoskeleton

    Function
    Provides shape and interenal organization

    network of protein filaments
  3. Microfilament
    • threadlike protein
    • (actin)
  4. Actin
    assemply/disassembly of actin is responsible for cytoplasmic movement
  5. microtubules
    • made of tubulin
    • maintain cell shape
    • critical during mitosis
  6. tubulin
    hollow tubes of protein
  7. Compare-Contrast Actin & Tubulin
    • Actin is a thin thread like protein, tubulin is a hollow tube.
    • Actin is for movement, tubulin for cell shape
  8. Cell Membrane Structures
    Microvilli, Cilia, Flagella
  9. Demosones
    Knex of cells
  10. Ribosome

    Function

    Special difference in organelle
    • Makes proteins using Translation
    • Ribosome= TRNA anticodon + Amino Acid ---Protein

    not lipid bilayer
  11. ER

    2 Types
    Functions
    • -Protein Synthesis-
    • Site where protein exported from cell
    • Site where lipid components of cell mem assembled

    • Rough- involved in protein syn
    • smooth- involved in nonprotein syn
  12. Golgi Apparatus

    Func
    • hold proteins made by Rough ER
    • --modifies sorts packages proteins for storage (in lysosomes) or for exporrt
  13. Lysosomes

    Func
    • produced by golgi
    • small sacs filled with digestive enzymes
  14. Peroxisomes
    • smaller than lysosomes
    • made by Rough ER
    • NEUTRALIZE TOXINS (like alcohol)
  15. Mitochondria
    • Cell resperation
    • Convert food E into Usable E
    • Double Membrane-
  16. Chloroplasts

    Where?
    PLANTS ONLY

    Capture E from sun-- photosynthesis-- glucose

    double membrane

    Stroma- space between pancakes (GRANA) where calvin cycle takes place (makes glucose + O2)
  17. Robert Hooke
    1665- thin sections of cork, square cubes called CELLS
  18. Schleiden
    all plants made of cells
  19. Schwann
    all animals made of cells
  20. Virchow
    • both animals & plants have cells
    • COmpeltes cell theory
  21. Leeunwenhoek
    tiny organisms in pond water
  22. CELL THEORY
    • 1.) All living things made of cells.
    • 2.) Cells are basic struc/func of all living things
    • 3.) New cells come from pre existing cells
  23. Prokaryotic Cell-
    • NO nucleus
    • Bacteria
  24. Eukaryotic
    • NUCLEUS,
    • larger more complex than pro
    • vary from single cell to multi cellular organisms
  25. ALL CELLS HAVE....
    • cell membrane
    • DNA (at some point)
  26. 2 Major Parts in Euk Cell Struc
    • Nucleus
    • Cytoplasm
  27. Cell Membrane

    Func
    determines what goes in/out of cell

    • selectively permeable or semipermeable
    • composed of lipids and proteins
