Outline the cell theory. - correct answer Living organisms are composed of cells. Cells are the smallest unit of life. Cells come from pre-existing cells. Discuss the evidence for the cell theory. - correct answer The nature of scientific theories could be introduced here: the accumulation of evidence that allows a hypothesis to become a theory; whether a theory should be abandoned when there is evidence that it does not offer a full explanation; and what evidence is needed for a theory...
