Which of the following structures is found inside a prokaryotic cell?

• A. Ribosome
• B. Nucleus
• C. Chloroplast
• D. Mitochondria

Answer: (A)

Verified step by step guidance

1. Understand the basic structure of prokaryotic cells: Prokaryotic cells are simpler than eukaryotic cells and lack membrane-bound organelles.
2. Identify the structures listed in the options: Nucleus, Chloroplast, Mitochondria, and Ribosome.
3. Recall that prokaryotic cells do not have a nucleus or any other membrane-bound organelles like chloroplasts and mitochondria.
4. Recognize that ribosomes are non-membrane-bound structures responsible for protein synthesis and are present in both prokaryotic and eukaryotic cells.
5. Conclude that the structure found inside a prokaryotic cell from the given options is the ribosome.
