Detailed explanation-1: -Detailed Solution. The correct answer is Mitochondria. As they are prokaryotes, bacteria do not usually have membrane-bound organelles in their cytoplasm, and thus contain few large intracellular structures. They lack a true nucleus, mitochondria, chloroplasts, and the other organelles present in eukaryotic cells.

Detailed explanation-2: -Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do. However, photosynthetic bacteria, such as cyanobacteria, may be filled with tightly packed folds of their outer membrane.

Detailed explanation-3: -The correct option is C Nucleus.

Detailed explanation-4: -Bacteria do not have mitochondria. Bacteria and archaea lack any membrane-bound organelles.

Detailed explanation-5: -Mitochondria is a membrane bound cell organelle. Such membrane bound cell organelles are absent in prokaryotic cells like bacteria.
