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: -Prokaryotic cells are believed to be the oldest cells on Earth. Thus, all bacteria are prokaryotic, but not all prokaryotes are bacteria. The other major group of prokaryotes is the blue green algae (also known as cyanobacteria).

Detailed explanation-3: -Final answer: Ribosomes are common in both eukaryotes and prokaryotes.

Detailed explanation-4: -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.
