What is the major difference between prokaryotic and eukaryotic?
A
prokaryotic has a nucleus; eukaryotic does not
B
eukaryotic has a nucleus; prokaryotic does not
C
prokaryotic has DNA; eukaryotic does not
D
eukaryotic has a cell wall; prokaryotic does not
Explanation: 

Detailed explanation-1: -What is the difference between Prokaryotic and Eukaryotic cells? The defining characteristic feature that distinguishes between prokaryotic and eukaryotic cell is the nucleus. In prokaryotic cells, the true nucleus is absent, moreover, membrane-bound organelles are present only in eukaryotic cells.

Detailed explanation-2: -Note that eukaryotic cells likely evolved from a symbiotic relationship between two prokaryotic cells, whereby one set of prokaryotic DNA eventually became separated by a nuclear envelope and formed a nucleus.

Detailed explanation-3: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
