Which two features are present in eukaryotic cells but absent in prokaryotic cells?

• A. Nucleus and membrane-bound organelles
• B. DNA and RNA
• C. Cell wall and ribosomes
• D. Plasma membrane and cytoplasm

Answer: (A)

Verified step by step guidance

1. Understand the basic differences between eukaryotic and prokaryotic cells. Eukaryotic cells have a more complex structure compared to prokaryotic cells.
2. Identify the key structural components of eukaryotic cells: they have a nucleus and various membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
3. Recognize that prokaryotic cells, such as bacteria, do not have a nucleus. Their genetic material is not enclosed within a membrane.
4. Note that prokaryotic cells lack membrane-bound organelles. Their cellular functions occur in the cytoplasm or are associated with the cell membrane.
5. Compare the options given: 'Nucleus and membrane-bound organelles' are features unique to eukaryotic cells, whereas the other options include features that are present in both cell types.
