Detailed explanation-1: -Bacteria are classified as prokaryotes, along with another group of single-celled organisms, the archaea. Prokaryotes are tiny, but in a very real sense, they dominate the Earth. They live nearly everywhere – on every surface, on land and in water, and even inside of our bodies.
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: -Prokaryotic cells have a single, circular, and naked (without histone proteins) DNA molecule that is not contained within a nucleus. Prokaryotic cells are believed to be the oldest cells on Earth. Thus, all bacteria are prokaryotic, but not all prokaryotes are bacteria.
Detailed explanation-4: -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-5: -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.
