Question

The organelles that are present in eukaryotes but not in prokaryotes is/are:

• A. Nucleus
• B. Mitochondria
• C. Ribosome
• D. Both A and B
  
• E. Both A and C
  

Answer 1

The correct option is D Both A and B

• Prokaryotes are unicellular organisms that lack membrane-bound cell organelles. Nucleus and mitochondria are double membrane-bound organelles and hence, are absent in prokaryotic cells.
• Ribosomes are organelles made up of proteins and RNA molecules called subunits and do not have any membrane. These are involved in protein synthesis and are present in both prokaryotes (70S type) and eukaryotes (80S type).

Therefore, the correct answer is option D.
