The presence of which of the following feature would best indicate a eukaryotic cell?
Correct answer: B. Membrane bound organelles
- A. Cilia
- B. Membrane bound organelles
- C. Plasma membrane
- D. Ribosomes
Explanation
Option B is correct since eukaryotic cells always possess organelles that are membrane-bound. Option A is incorrect since only some eukaryotic cells may possess motile or nonmotile cilia. Therefore, cilia is not a necessary feature of all eukaryotic cells. Option C is incorrect since all prokaryotic cells also possess a plasma membrane. While the plasma membrane is a major component of all eukaryotic cells, the presence of a membrane in prokaryotes makes it difficult to differentiate between the two cells based on the cell membrane. Option D is incorrect since ribosomes are found in both prokaryotic and eukaryotic cells. In eukaryotes, 80S ribosomes are present while in prokaryotes, 70S ribosomes are present.
