Which of the following structures is present in both prokaryotes and eukaryotes?
Correct answer: A. Cell membrane
- A. Cell membrane
- B. Golgi apparatus
- C. Mitochondria
- D. Nucleoid
Explanation
The correct answer is the cell membrane, as it is the universal cellular structure that is present in both prokaryotic and eukaryotic cells. It functions as a selective barrier that allows cells to maintain homeostasis by controlling the movement of substances in and out of the cell. In contrast, the Golgi apparatus and mitochondria are organelles specific to eukaryotes, while the nucleoid is a characteristic of prokaryotic cells. Thus, the cell membrane is the only structure common to both types of cells.
