Question

Following are prokaryotic cells EXCEPT _________

• A. Anabaena
• B. Streptococcus
• C. Nostoc
• D. Paramoecium

Hint:

{All bacteria and cyanobacteria are prokaryotic; protozoans are eukaryotic}.

Answer 1

The Correct Option is D

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.
