cells.[4] Cells emerged on Earth at least 3.5 billion years ago. Cell Theory: In biology‚ cell theory is a scientific theory that describes the properties of cells‚ the basic unit of structure in every living thing. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory is one of the foundations of biology. The three parts to the cell theory are as described below: All living organisms
