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: -Eukaryotic cells have a nucleus, a membrane-bound chamber where DNA is stored, while prokaryotic cells don’t. This is the feature that formally separates the two groups. Eukaryotes usually have other membrane-bound organelles in addition to the nucleus, while prokaryotes don’t.

Detailed explanation-3: -Examples of prokaryotes are blue-green algae, bacteria and mycoplasma. Among prokaryotes, bacteria are the most common and multiply very fast. They are single-celled and range in size from 0.2 to 10 microns (about 10 times smaller than most plant and animal cells).

Detailed explanation-4: -A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.

Detailed explanation-5: -Prokaryotic cells do not have a nucleus. All cells can are classified as prokaryotic or eukaryotic based on their internal structure. Eukaryotic cells contain a nucleus-a structure enclosed in a membrane that contains the majority of the cell’s genetic material.
