Ribosomes are non-membrane bound organelles found in all cells – both eukaryotic as well as prokaryotic. Within the cell, ribosomes are found not only in the cytoplasm but also within the two organelles – chloroplasts (in plants) and mitochondria and on rough ER.
Assertion (A): Eukaryotic cells have ribosomes in multiple cellular locations. Reason (R): Within the cell, ribosomes are found only in the cytoplasm and not in any organelles.
Correct answer: C — If assertion is true but reason is false.
The Assertion is true - NCERT describes ribosomes in multiple locations. However, NCERT states “Within the cell, ribosomes are found not only in the cytoplasm but also within the two organelles – chloroplasts (in plants) and mitochondria and on rough ER.” The Reason falsely limits ribosomes to cytoplasm only.
