Question

Which of the following will comprise the most appropriate feature of prokaryotic cells that distinguished them from the eukaryotic cells?

• A. Lack of nuclear membranes and lack of membrane-bound organelles like plastid and mitichondria
• B. Have dispersed DNA
• C. Lack of ribosomes
• D. Biochemistry being fundamentally different

Answer 1

Answer: (A)

Lack of nuclear membranes and lack of membrane-bound organelles like plastid and mitichondria

Prokaryotic cells are the cells that lack well-developed, membrane bound nucleus and organelles like plastid and mitochondria. They possess dispersed form of nucleus called as the nucleoid. The ribosome is the only organelle that present in both the cells, in prokaryotes, it is 70S and in eukaryotes, it is 80S. Thus, the correct answer is option A.
