Verified step by step guidance1
Understand the context of the question: The problem is asking about the principles of cell theory, which is a foundational concept in biology describing the properties of cells.
Recall the three main tenets of cell theory: (1) All living organisms are composed of one or more cells, (2) The cell is the basic unit of structure and function in living organisms, and (3) All cells arise from pre-existing cells through cell division.
Evaluate each statement in the question against the principles of cell theory: (a) 'All living organisms are composed of one or more cells' aligns with the first tenet of cell theory. (b) 'Cells can arise spontaneously from non-living matter' contradicts the third tenet, as cells arise from pre-existing cells. (c) 'Cells do not require energy to function' is incorrect because cells require energy for processes like metabolism and growth. (d) 'Only plant cells contain genetic material' is false because all cells, including animal cells, contain genetic material.
Identify the correct statement: Based on the evaluation, the statement 'All living organisms are composed of one or more cells' is consistent with cell theory.
Conclude that the correct answer is the first statement, as it directly reflects one of the core principles of cell theory.
