Q: Identify the component that is found only in eukaryotic cells-
  • A. Plasma membrane
  • B. Nuclear membrane
  • C. Ribosome
  • D. Cytoplasm
Correct Answer: Option B - Eukaryotic cells are characterized by the presence of a nucleus surrounded by a complex nuclear membrane, which is not found in prokaryotic cells. While ribosomes are present in both eukaryotic and prokaryotic cells, the nuclear membrane is unique to eukaryotic cells. Plasma membrane and cytoplasm are also common to both cell types.
