Question

The only cell organelle seen in a prokaryotic cell is:

• A. Mitochondria
• B. Ribosomes
• C. Plastids
• D. Lysosomes

Answer 1

The correct option is B

Ribosomes

The correct option is B:

Explanation of the correct option:

1. The only cell organelle seen in a prokaryotic cell is Ribosomes.
2. A prokaryotic cell is a primitive cell that does not have a true nucleus and double-membrane bound organelles like- mitochondria, Endoplasmic reticulum, Golgi apparatus, plastids, lysosomes, etc.
3. It only has DNA that is coiled and found in the cytoplasm (nucleoid) along with ribosomes.
4. The ribosome is the only cell organelle that is freely found in the cytoplasm of a prokaryotic cell and synthesizes proteins within the cell.
5. Only Eukaryotic cells have double-membrane bound organelles in their cytoplasm like- mitochondria, Endoplasmic reticulum, Golgi apparatus, plastids, lysosomes, etc.

Explanation of the incorrect options:

Option A:

Mitochondria are found in a eukaryotic cell.

Option C:

Plastids are found in a eukaryotic cell.

Option D:

Lysosomes are found in a eukaryotic cell.

Final answer: The only cell organelle seen in a prokaryotic cell is ribosomes.
