Detailed explanation-1: -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.

Detailed explanation-2: -Bacteria are examples of the prokaryotic cell type. An example is E. coli. In general, prokaryotic cells are those that do not have a membrane-bound nucleus.

Detailed explanation-3: -Escherichia coli bacterium. Streptococcus bacterium. Streptomyces soil bacteria.

Detailed explanation-4: -All bacteria are prokaryotes, and while they may have other cellular structures such as a cell wall, cilia, or flagella, they lack a nucleus, making them prokaryotic. There is only one other type of cell that is prokaryotic, which is archaea, single-celled organisms that are related to bacteria.

Detailed explanation-5: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
