C
Plasma membrane
D
Chloroplasts
Verified step by step guidance1
Understand the difference between prokaryotic and eukaryotic cells: Prokaryotic cells lack membrane-bound organelles, while eukaryotic cells have them. This distinction is key to identifying which structures are shared.
Review the function and presence of the plasma membrane: The plasma membrane is a universal feature of all cells, as it regulates the movement of substances in and out of the cell and provides structural support.
Analyze the nucleus: The nucleus is a membrane-bound organelle that houses genetic material and is exclusive to eukaryotic cells. Prokaryotic cells have a nucleoid region instead, which is not membrane-bound.
Examine mitochondria and chloroplasts: Both are membrane-bound organelles involved in energy production and photosynthesis, respectively. These structures are only found in eukaryotic cells.
Conclude that the plasma membrane is the correct answer: It is the only structure listed that is present in both prokaryotic and eukaryotic cells, as it is essential for all cell types.
