The presence of which of these cell structures would confirm that the cell is prokaryotic?
Correct answer: D. Peptidoglycan cell wall
- A. Cytoplasm
- B. Ribosomes
- C. Flagella
- D. Peptidoglycan cell wall
Explanation
The presence of a peptidoglycan cell wall is a unique characteristic of most prokaryotic cells, distinguishing them from eukaryotic cells, which do not have peptidoglycan. This rigid layer provides structural support and protection, making it a strong indicator of prokaryotic cells. In contrast, cytoplasm, ribosomes, and flagella are found in both prokaryotic and eukaryotic cells, and thus their presence cannot confirm that a cell is prokaryotic.
