Step-by-step explanation:
The statement that is not true about the cell theory is: "all cells are made up of specialized organelles." The cell theory states that all living things are composed of one or more cells, that all cells are the basic unit of structure of living things, and that all cells come from pre-existing cells. However, not all cells have specialized organelles. Some cells, such as prokaryotic cells, do not have membrane-bound organelles like mitochondria or chloroplasts.
