Question

______ is found in eukaryotic cells but not in prokaryotic cells.

• A. Ribosomes
• B. Plasma membrane
• C. Well-defined nucleus
• D. Cell wall
• E. All of the above

Answer 1

Answer: (C)

Well-defined nucleus

Eukaryotic cells differ from prokaryotic cells in having a well-defined nucleus with a nuclear membrane. The prokaryotic cells have a primitive nucleus without a nuclear membrane, where the nuclear material lies freely in the cytoplasm.

The cell wall is present in a prokaryotic cell and in some of the eukaryotic cells. Ribosome and plasma membrane are present in both eukaryotic and prokaryotic cells.

Thus, the correct answer is option C.
