Question

Eukaryotic cell differs from prokaryotic cell in having

• A. Single envelop system
• B. Nucleoid
• C. 70S ribosomes
• D. Nucleus

Answer 1

The correct option is D Nucleus

A prokaryotic organism does not have a membrane-bound nucleus or a true nucleus. Instead of a nucleus, nucleoids are seen. It also lacks many of the membrane-bound organelles but contains ribosomes, cytoplasm, etc. But eukaryotic organisms possess a true membrane-bound nucleus.

So the correct answer is the nucleus.
