A

B
All cells contain a membrane-bound nucleus.
C
All cells arise from pre-existing cells.
D
All living organisms are composed of one or more cells.
Verified step by step guidance1
Step 1: Recall the three main tenets of the classical cell theory, which are: (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.
Step 2: Analyze each statement given in the problem and compare it to the classical cell theory tenets.
Step 3: Identify that the statement 'All cells contain a membrane-bound nucleus' is not part of the classical cell theory because it is specific to eukaryotic cells, whereas the classical cell theory applies to all cells, including prokaryotes which lack a membrane-bound nucleus.
Step 4: Confirm that the other statements align with the classical cell theory principles.
Step 5: Conclude that the statement about the membrane-bound nucleus is the one NOT part of the classical cell theory.
