How do prokaryotic cells differ from eukaryotic cells in terms of their cellular structure?

• A. Prokaryotic cells have a complex cytoskeleton, while eukaryotic cells do not.
• B. Prokaryotic cells contain chloroplasts, while eukaryotic cells do not.
• C. Prokaryotic cells have mitochondria, while eukaryotic cells do not.
• D. Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.

Answer: (D)

Verified step by step guidance

1. Begin by understanding the basic definitions: Prokaryotic cells are simpler, single-celled organisms without a nucleus, while eukaryotic cells are more complex and can be single-celled or multicellular, with a defined nucleus.
2. Examine the cellular structures: Prokaryotic cells lack membrane-bound organelles, such as the nucleus, mitochondria, and chloroplasts, which are present in eukaryotic cells.
3. Focus on the nucleus: The key difference is that prokaryotic cells do not have a nucleus; their genetic material is located in a nucleoid region, whereas eukaryotic cells have a nucleus that houses their DNA.
4. Consider the cytoskeleton: Eukaryotic cells have a complex cytoskeleton that provides structural support and facilitates movement, while prokaryotic cells have a simpler structure.
5. Review the options given: The correct statement is that prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus, which is a fundamental distinction between these two types of cells.
