Question:
Following are prokaryotic cells EXCEPT _________
Following are prokaryotic cells EXCEPT _________
Show Hint
{All bacteria and cyanobacteria are prokaryotic; protozoans are eukaryotic}.
Updated On: Mar 6, 2026
- Anabaena
- Streptococcus
- Nostoc
- Paramoecium
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding prokaryotic cells.
Prokaryotic cells lack a true nucleus and membrane-bound organelles. They include bacteria and cyanobacteria.
Step 2: Analysis of given organisms.
Anabaena and Nostoc are cyanobacteria and hence prokaryotic.
Streptococcus is a bacterium and is prokaryotic.
Paramoecium is a unicellular eukaryote with a true nucleus.
Step 3: Conclusion.
Therefore, the organism which is not prokaryotic is Paramoecium.
