• B. Cell membrane and mitochondria
• C. Nucleus and cell wall
• D. Cell membrane and cell wall

Answer: (D)

Verified step by step guidance

1. Understand that prokaryotic cells are simpler than eukaryotic cells and do not contain membrane-bound organelles such as a nucleus or mitochondria.
2. Recognize that the cell envelope in prokaryotes typically includes structures that protect and give shape to the cell.
3. Identify the two main components of the prokaryotic cell envelope: the cell membrane and the cell wall.
4. The cell membrane, also known as the plasma membrane, is a lipid bilayer that controls the movement of substances in and out of the cell.
5. The cell wall is a rigid structure that provides additional support and protection, and is located outside the cell membrane.
