Question

Living organisms are grouped into eukaryotes and prokaryotes on the basis of ____________.

• A. Nucleus
• B. Ribosomes
• C. Plasma membrane
• D. None of the above

Answer 1

The correct option is A Nucleus

Eukaryotic cells have a well-defined nucleus with a nuclear membrane whereas prokaryotic cells do not have a well-defined nucleus and nuclear membrane. Apart from the nucleus, other membrane-bound organelles like mitochondria, lysosomes, and Golgi complex, etc. are also absent in prokaryotes. However, plasma membrane, cytoplasm, and ribosomes are present in both cell types.

Hence the correct option is A.
