The main difference between a prokaryotic and a eukaryotic cell is that a prokaryotic cell has
- A. no ribosomes
- B. no membrane bound nucleus or organelles
- C. no genetic material
- D. no plasma membrane
Explanation
Prokaryotes keep their DNA in a nucleoid region with no surrounding envelope and have no mitochondria, endoplasmic reticulum or Golgi apparatus. They do have ribosomes, though the 70S type rather than the 80S type of the eukaryotic cytoplasm, and that difference is exactly what several antibiotics exploit. Every cell has genetic material and a plasma membrane.
