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.

Detailed explanation-2: -Bacteria cells are prokaryotes, which means they do not have many of the organelles that eukaryotic cells have. Therefore, and most importantly, bacteria cells do not have a nucleus.

Detailed explanation-3: -All the prokaryotic organisms lack membrane-bound organelles and a well-defined nucleus. Since bacteria are prokaryotic organisms, they do not have a nucleus.

Detailed explanation-4: -Bacteria, of course, have no nucleus and therefore also nuclear membrane. genetic information-DNA is organized into numerous chromosomes and is packaged in the nucleus.

Detailed explanation-5: -Prokaryotes are unicellular organisms that are devoid of a nucleus and membrane-bound organelles. The prokaryotic cytoplasm carries the genetic material in the form of DNA which is usually round in shape.
