Verified step by step guidance
1
Understand the basic definitions: Prokaryotic cells are simple, single-celled organisms without a nucleus or membrane-bound organelles. Eukaryotic cells are more complex and have a nucleus and membrane-bound organelles.
Identify the key structural difference: The presence or absence of a nucleus is a fundamental distinction. Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.
Evaluate the options: Compare each statement to the known characteristics of prokaryotic and eukaryotic cells.
Analyze the first option: Prokaryotic cells do not have membrane-bound organelles, so this statement is incorrect.
Confirm the correct answer: The statement 'Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus' accurately describes the primary difference between these cell types.
