Which statement is true about bacteria's mitochondria?

• A. Bacteria have mitochondria in their cytoplasm.
• B. Bacteria lack mitochondria in their cytoplasm.
• C. Bacteria have mitochondria only in host cells.
• D. Bacteria have multiple mitochondria.

Answer: (B)

Mitochondria are membrane-bound organelles found in eukaryotic cells, designed to produce most of the cell’s energy. Bacteria are prokaryotes and do not have membrane-bound organelles such as mitochondria. Their energy-generation processes occur across the cell membrane and in the cytoplasm rather than inside any mitochondrion. Therefore, stating that bacteria lack mitochondria in their cytoplasm is true. Saying bacteria have mitochondria, or that they exist only in host cells, or that bacteria have multiple mitochondria, would not fit because bacteria do not possess mitochondria at all.
