Which of the following is ABSENT in Prokaryotic cells:
Correct answer: A. Mitochondria
- A. Mitochondria
- B. Circular DNA
- C. Ribosomes
- D. Cell membrane
Explanation
Prokaryotic cells have no membrane bound organelles, so mitochondria are absent and respiration happens on the cell membrane. Circular DNA, 70S ribosomes and a cell membrane are all present in prokaryotes, which is why they are the tempting but wrong choices.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
