Detailed explanation-1: -So, the correct answer is ‘Prokaryotic cells do not have a membrane-bounded nucleus, but eukaryotic cells do have such nucleus’.

Detailed explanation-2: -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-3: -All cells have a plasma membrane, DNA, and proteins. Of the choices given, the most reliable way to tell the difference between cell types is the presence of a well-defined nucleus, which is found only in eukaryotes.

Detailed explanation-4: -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.
