• A. (a) and (b) are wrong, (c) is correct
• B. (a) is correct, (b) and (c) are wrong
• C. (a) and (b) are correct, (c) is wrong
• D. (a), (b) and (c) are wrong
• E. (a) and (c) are correct (b) is wrong

Answer 1

Answer: (D)

• Nuclear membrane, chloroplast, mitochondria and microtubules are absent in prokaryotic cells. Pili are present in prokaryotic cells.
• Nuclear membrane, chloroplast, mitochondria and microtubules are present in eukaryotic cells
• Ribosomes are 70 S in prokaryotic cells chloroplast and mitochondria. They are 80 S in animal cells.
