| 914847033 | Robert Hooke (1665) | English scientist who observed cork under a microscope. First to use the word "cell" in reference to biology. | 1 | |
| 914847034 | Antoni van Leeuwenhoek (1632-1723) | Dutch pioneer microscopist who was among the first to observe single-celled organisms, sperm cells, red blood cells, etc. Often called the father of microbiology. | 2 | |
| 914847035 | Robert Brown (1833) | Scottish botanist who was the first to observe nucleus | 3 | |
| 914847036 | Matthias Schleiden (1838) | German physiologist and histologist who observed that embryonic plants came from just one cell. Also helped formulate Cell Theory. | 4 | |
| 914847037 | Theodor Schwann (1839) | German physiologist and histologist who formulated Cell Theory. | 5 | |
| 914847038 | Louis Pasteur (1860) | French microbiologist who modified the Cell Theory to include that cells must come from pre-existing cells. | 6 | |
| 914847039 | Cell Theory | All organisms have 1 or more cells; the cell is the basic unit of structure for all cells; all cells must come from pre-existing cells. | 7 | |
