What are the main points of cell theory?
- All living things are made up of one or more cells.
- The cell is the structural and functional unit of all living things.
- Cells come from pre-existing cells through the process of division.
- All cells are the same in regard to chemical composition.
Why is the cell theory a theory and not a law quizlet?
A theory tries to explain why things happen and it can be changed or revised with new evidence. Theories never become laws since they each have different use.

What best describes a scientific theory?
A scientific theory is a well-tested broad explanation of a natural phenomenon. In everyday life we often use the word theory to mean a hypothesis or educated guess but a theory in the context of science is not simply a guess—it is an explanation based on extensive and repeated experimentation.
What makes a theory a good theory?
What makes a theory useful? … One lesson is that the reason a “good” theory should be testable be coherent be economical be generalizable and explain known findings is that all of these characteristics serve the primary function of a theory–to be generative of new ideas and new discoveries.
What is scientific theory example?
What is meant by the cell theory?
