Which of the following is true about prokaryotic and eukaryotic cells?

• A. Both prokaryotic and eukaryotic cells have membrane-bound organelles.
• B. Prokaryotic cells have a complex cytoskeleton, while eukaryotic cells do not.
• C. Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.
• D. Eukaryotic cells are generally smaller than prokaryotic cells.

Answer: (C)

Verified step by step guidance

1. Understand the basic differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and do not have a nucleus or other membrane-bound organelles, while eukaryotic cells have a nucleus and various membrane-bound organelles.
2. Evaluate the statement: 'Both prokaryotic and eukaryotic cells have membrane-bound organelles.' Prokaryotic cells lack membrane-bound organelles, so this statement is false.
3. Evaluate the statement: 'Prokaryotic cells have a complex cytoskeleton, while eukaryotic cells do not.' Prokaryotic cells have a simpler cytoskeleton compared to the complex cytoskeleton found in eukaryotic cells, making this statement false.
4. Evaluate the statement: 'Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.' This is a true statement, as it correctly describes the presence of a nucleus in eukaryotic cells and its absence in prokaryotic cells.
5. Evaluate the statement: 'Eukaryotic cells are generally smaller than prokaryotic cells.' Eukaryotic cells are generally larger than prokaryotic cells, so this statement is false.
