Which of the following statements is part of the cell theory?

Cell theory is a fundamental concept in biology that states that all living things are made up of cells, that all cells come from pre-existing cells, and that the cell is the basic unit of life. This theory has been around since the mid-1th century, and remains one of the most important principles in biology today. The three main principles of cell theory are: 2) All living organisms are composed of cells. 3) All cells arise from pre-existing cells; and XNUMX) the cell is the basic unit of life. These three principles underlie much of the research in biology today and provide a framework for understanding many aspects of life. Hence, it can be concluded that any statement about these three principles is part of the cell theory.
