Question

Ribosomes are found in:

• A. Cytoplasm and nucleus
• B. Golgi complex and nucleus
• C. Mitochondria and bacterial cell
• D. Endoplasmic Reticulum and Golgi complex

Answer 1

The correct option is C

Mitochondria and bacterial cell

The correct option is C:

Explanation of the correct option:

1. Ribosomes are the site of protein synthesis.
2. In eukaryotic cells, mitochondria have ribosomes of 70S type.
3. Bacterial cells contain ribosomes in their cytoplasm.
4. So, ribosomes are present in both mitochondria and bacterial call.

Explanation of the incorrect option(s):

Option A:

1. Ribosomes are present freely in the cytoplasm.
2. Protein synthesis does not take place in the nucleus.
3. So, the nucleus does not contain ribosomes.

Option B:

1. Golgi complex is associated with the packaging of protein, it does not synthesize it.
2. Both the Golgi complex and nucleus do not contain ribosomes.

Option D:

1. Ribosomes are present on the surface of Endoplasmic Reticulum (RER).
2. But it is not present in the Golgi complex.

Final answer: Ribosomes are found in Mitochondria and bacterial cells.
