What is Cell Theory? |
1. All living things are made of cells 2. Cells are the basic structural and functional unit of organisms 3. All cells are from pre-existing cells |
|
How did Robert Hooke contribute to the development of cell theory? |
In 1663, Robert Hooke introduced the term 'cell' |
|
How did Robert Brown contribute to the development of cell theory? |
In 1801, Robert Brown discovered the nucleus in cells |
|
|
What is the significance of technological advances to developments in cell theory? |
Without technological advances the cell theory could not have happened. The microscope enabled us to see cells. The staining of the cells enabled division of the nucleus in cell division to be observed. |
