1. What is it?
1.1. three main ideas
1.1.1. all living organisms are made of cells
1.1.2. Cells are alive and the basic living units of organization in all organisms
1.1.3. All cells come from other cells
2. Experiments
2.1. Antoni van Leeuwenhoek
2.1.1. grinded lenses to create microscopes
2.1.2. Significance to Science
2.1.2.1. Created a platform for microscopes to be invented, which many people used every day.
2.2. Robert Hooke
2.2.1. discovered bacteria and protozoa in cork cells using Leeuwenhoek's microscope
2.2.1.1. Significance to Science
2.2.1.1.1. Showed that cork is a living things with tiny little cells.
2.3. Matthias Jakob Schleiden
2.3.1. observed plant cells under a microscope and discovered that all plants/plant parts are made of cells
2.3.1.1. Significance to Science
2.3.1.1.1. Science uses experimentation and observation to understand the natural world
2.4. Theodor Schwann
2.4.1. observed animal tissue under a microscope and concluded that all living things are made of cells
2.4.1.1. Significance to Science
2.4.1.1.1. Helped form cell theory that many scientists use every day (All living things are made of cells)
2.5. Rudolf Virchow
2.5.1. said all living cells must come from previous living cells
2.5.1.1. Significance to Science
2.5.1.1.1. Crazy idea at the time but now helps scientists every day
2.6. Louis Pasteur
2.6.1. disproved "spontaneous generation" idea with a famous experiment
2.6.1.1. took two flasks with broth- one straight necked and one with an "S" shaped neck. burned each to sterilize and left out for a few weeks
2.6.1.2. after a few weeks, the broth in the straight necked bottle was discolored, while the broth in the "S" necked bottle was the same
2.6.1.3. shows that bacteria cannot spontaneously generate
2.6.1.3.1. Significance to Science
