Cell Theory

Cell Theory

Cells are the basic unit of structure and reproduction in all organisms. After the discovery of the cell by Robert Hooke, other scientists added important contributions to cell theory. Cell theory describes the properties of cells. These studies were the beginning of cellular biology, and they were fueled by advancements in functionality and magnification of microscopes.
