Detailed explanation-1: -The bacteria are the oldest and simplest living organisms, and all of the bacteria are “prokaryotes, ‘’ meaning that they do not have a true membrane-bound nucleus as eukaryotes do.

Detailed explanation-2: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.

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.
