Which of these is a characteristic of prokaryotic cells?
Correct answer: D. All of these
- A. Absence of membrane bound organelles
- B. Absence of nucleus
- C. Presence of 70S ribosomes
- D. All of these
Explanation
Option D is correct since a prokaryotic cell does not have membrane-bound cellular organelles and a nucleus. It contains 70S ribosomes. Option A is incorrect since it states only one out of the three correct options. Option B is incorrect since it states only one out of the three correct options. Option C is incorrect since it states only one out of the three correct options.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
