| A cell theory is currently being proposed to explain the mechanisms of these two phenomena. |
| The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life comes from preexisting life. |
| The science of molecular biology would be most capable of overthrowing the cell theory if the latter were an exaggerated generalization. |
| Although biochemistry might have made considerable progress without cell theory, each influenced the other almost from the start. |
| The cell theory is one of the foundational tenets of biology and explains the relationship between cells and living things. |
| Globular theories, the precursor to the cell theory, were quite popular at the beginning of the 19th century. |
