Detailed explanation-1: -A prokaryotic cell doesn’t have a nuclear membrane around the nucleus. The nucleus without a nuclear membrane is called the naked nucleus and it is not considered as a true nucleus. So prokaryotic cells don’t have a true nucleus.
Detailed explanation-2: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.
Detailed explanation-3: -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-4: -The organisms in Domains Bacteria and Archaea are prokaryotic, meaning that their cells do not have a true nucleus, but rather have a nuclear region.
Detailed explanation-5: -Hint: Prokaryotes are organisms that lack the true nucleus because they do not contain an envelope surrounding the nuclear membrane.
