1. Shape support and protection. Made of cellulose.
    Cell Wall
  2. Phospholipid bilayer. Regulates what passes in and out of the cell. Semi-permeable membrane that separates cytoplasm from environment.
    Cell Membrane
  3. Site of photosynthesis. Contain chlorophyll.
  4. Site of cellular respiration. Powerhouse of the cell. ATP
  5. Produce proteins. Attached to ER=proteins are exported. Free-floating=proteins are used in the cell.
  6. Most cell activities occur here! Transports dissolved materials throughout cell.
  7. Control center, directs all activities. Contains DNA, makes RNA.
  8. Regulates what passes in and out of the nucleus. Semi-permeable membrane that separates nucleus from cytoplasm.
    Nuclear Membrane
  9. DNA and proteins. Coil to form chromosomes during reproduction.
  10. Makes and partially assembles ribosomes.
  11. Digestion. Recycles cell parts.
  12. Transports proteins throughout cell. Smooth=no ribosomes. Rough=ribosomes attached.
    Endoplasmic Reticulum
  13. Packages substances made in cell for export.
    Golgi Apparatus
  14. Support, movement, cell division. Found throughout cell.
  15. Storage for food, water, waste. Takes up most available space in plant cells. Turgor Pressure
  16. Movement. Found in bacteria, protists and animal cells.
    • Flagella
    • Cilia
  17. "Before nucleus" – cells with NO nucleus or membrane-bound organelles (such as ER)
  18. "True nucleus" – cells WITH a nucleus and membrane-bound organelles.
  19. eukaryote - Cell wall, chloroplast, vacuole
    Plant Cell
  20. eukaryote - cilia, flagella
    Animal Cell
  21. prokaryote - genome (large ring of DNA), plasmids (small circular DNA), cell wall with or without peptidoglycan
    Bacteria Cell
  22. eukaryote – cell wall with chitin
    Fungi Cell
  23. eukaryote – great diversity
    Protist Cell
  24. organelle→cell→tissue→organ→organ system→organism
    Multicellular organization
  25. Examined corks
    Coined the term cell
    Robert Hooke
  26. Made microscopes magnification of 50-300X.
    Observed first living cells while looking at blood, rainwater, teeth scrapings, etc.
    First documented sighting of bacteria, called them "wee animalcules".
    Anton van Leeuwenhoek
  27. Put meat in two jars. Open jar had maggots, the covered one did not.
    Refuted the theory of spontaneous generation (life can arise from non living things). No one believed him.
    Francesco Redi
  28. Boiled two flasks of meat broth. Sealed flask had no microorganisms in it, unsealed one did.
    Refuted spontaneous generation, no one believed him.
    Lazzaro Spallanzani
  29. Put boiled broth in two swan necked flasks. One year later, no bacterial growth. He broke the neck off the flask and there were microbes one day later. Refuted theory of spontaneous generation and was finally accepted.
    Louis Pasteur
  30. All plants are composed of cells.
    Matthias Schleiden
  31. All animals are composed of cells.
    Theodore Schwann
  32. Pathologist who studied diseases.
    Cells only come from other cells.
    Rudolf Virchow
