  1. Hans and Zacharias Jansen
    Discovered the first compound light microscope involving 2 lenses. has Maximum magnification of 9x.
  2. Robert Hooke
    in a drawing of cork, he saw little things moving and named them “cells”
  3. Anthony leeuwenhoek
    Inserted 550 lenses which created the mag. Of 270x and saw single-celled organisms and named them “animalcules”.
  4. Francesco Redi
    Observed that flies are attracted to rotted meat so he puts paper cover on one jar, no cover on one jar and a gauze on one jar and turned out that there’s only maggots on a jar with gauze.
  5. John Needham
    Made a theory that sterilized broth would become spoiled over time
  6. Louis Pasteur
    Disproved Needham’s theory because he said that the microorganisms come from air, whereas Needham didn’t put a cover on the broth so it got disproved
  7. Cell theory 1
    All organisms are composed of 1 or more cells
  8. Cell theory 2
    The cell is the smallest functional unit of life
  9. Cell theory 3
    All cells are produced from pre-existing cells
  10. Cell membrane
    The skin of the cell where it protects the whole cell
  11. Cytoplasm
    Jello like substance that keeps every organelles in its right shape
  12. Nucleus
    The brain of the cell. It contains ribosomes and nuclear envelope
  13. Ribosomes
    Like body builder where it makes protein for cells
  14. Rough ER.
    The gym where it holds all the ribosomes(proteins)
  15. Smooth ER.
    The candy shop where it makes lipids
  16. Vesicles
    Like an amazon package where it packs then send it to other locations
  17. Golgi body
    Like a restaurant where it gets raw materials then converts it in a fancy way then send it to somewhere
  18. Lysosomes
    the stomach of the cell where it spits out acids and have digestive enzymes(plant cells do not have lysosomes)
  19. Mitochondria
    Like battery or the energy source where it converts the stored chemical energy in sugar into usable
  20. Centrioles
    Helper. Helps a nucleus divide during cell division(most plant cells do not contain centrioles)
  21. Vacuoles
    The garage of the cell. It stores water, food particles and minerals(plant cells have one huge vacuoles)
  22. Chloroplast
    The chef, where they use solar energy, water and carbon dioxide to make glucose
  23. Cell wall
    The wall of the cell
  24. Prokaryotic cells
    Doesn’t have a nucleus
  25. Eukaryotic cells
    Has nucleus
