It is suspected that this cell is prokaryotic. 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
Option (d) suggests that the presence of a peptidoglycan cell wall would confirm that the cell is prokaryotic. This statement is correct. The presence of a peptidoglycan cell wall is a characteristic feature of prokaryotic cells, specifically bacteria. Prokaryotic cells have a rigid cell wall made of peptidoglycan, which provides structural support and protection to the cell. On the other hand, eukaryotic cells do not have a peptidoglycan cell wall.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
