AA membrane-bound nucleus
BA rigid outer cell wall
CA ribosome-rich cytosol
DA single plasma membrane
Answer & Solution
Correct answer: A. A membrane-bound nucleus
1. Both cell types share a plasma membrane, cytoplasm and ribosomes.
2. Only the eukaryotic cell wraps its DNA in a membrane, giving a true nucleus.
3. Cell walls appear in prokaryotes and in plants alike, so a wall cannot separate the two categories.
4. The distinguishing feature is a membrane-bound nucleus.
