In a phrase, tell what each scientist did to help develop the cell theory. Scientist o o_ Gontribution to Cell Theory 1. Hooke First to identify cells and name them 2. Leeuwenhoek Observed live cells and observed greater detail. 3. Schleiden Concluded that plants are made of cells. 4. Schwann 5. Virchow Concluded that animals and, in fact, all living things are made of cells. Proposed that all cells come from other cells. E o Ç) c 5 c eo o) -\o õ 6.

In the top left side of the Y shape below, write the characteristics of eukaryotic cells, In the top right side of the Y shape below, write the characteristics of prokaryotic cells. At the bottom of the Y shape beloq write the characteristics that both kinds of cells have in common, Then lightly cross out those characteristics at the top of the Y.
