To accurately address your question, it would help to know which options you're considering regarding the principles of cell theory. However, I can provide you with a brief overview of the fundamental principles of cell theory:
- All living organisms are composed of one or more cells.
- The cell is the basic unit of life.
- All cells arise from pre-existing cells.
If any option you have does not align with these principles, that would be the one that is NOT a principle of cell theory. If you share the specific options, I can help identify which one does not belong.
