Which of the following organelles are present in all the bacteria?
Correct answer: B. Ribosomes
- A. Mesosome
- B. Ribosomes
- C. Golgi bodies
- D. Mitochondria
Explanation
The correct answer is 'Ribosomes.' In bacteria, which are prokaryotic organisms, ribosomes are present and essential for protein synthesis. These are not membrane-bound and are found throughout the cytoplasm. Other options such as Golgi bodies, mitochondria, and chloroplasts are membrane-bound organelles found in eukaryotic cells, not in bacteria. Mesosomes were once thought to be a common organelle in bacteria, but they are now largely considered artifacts of cell preparation.
