Which of the following structures is found in eukaryotic but not prokaryotic cells?

• A. Cytosol
• B. Plasma membrane
• C. Ribosomes
• D. DNA
• E. Mitochondria

Answer: (E)

Verified step by step guidance

1. Understand the difference between eukaryotic and prokaryotic cells. Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.
2. Identify the structures listed in the problem: Cytosol, Plasma membrane, Ribosomes, DNA, and Mitochondria.
3. Recognize that Cytosol, Plasma membrane, Ribosomes, and DNA are found in both eukaryotic and prokaryotic cells.
4. Recall that mitochondria are membrane-bound organelles responsible for energy production and are found only in eukaryotic cells.
5. Conclude that the structure found in eukaryotic but not prokaryotic cells is mitochondria.
