Detailed explanation-1: -Prokaryotic cells are primitive cells which lack a nuclear membrane and in turn a well-defined nucleus. They also lack cellular organelles found in eukaryotic cells. Q. cells have a well-defined nucleus with a nuclear membrane, while cells lack a well-defined nuclear region.

Detailed explanation-2: –Prokaryotic cells are primitive as they lack membrane bound cell organelles. The genetic material of a prokaryotic cell is a single chromosome made up of a single strand of DNA. Prokaryotes have a cell membrane or plasma membrane that acts like a protective cover.

Detailed explanation-3: -Image: Sinauer Associates, Inc. A prokaryotic cell is a cell lacking a membrane-bounded nucleus or membrane-bounded organelles. Prokaryotic cells are thus more primitive than eukaryotic cells, which evolved from them. A prokaryotic organism, such as a bacterium, consists of single prokaryotic cell.

Detailed explanation-4: -Prokaryotes are primitive cells, without a nucleus or membrane bound organelles, has DNA located in a “nuclear area", but the DNA is not bound inside the nucleus as in Eukaryotes.

Detailed explanation-5: -Prokaryotic cells are simpler and lack the eukaryote’s membrane-bound organelles and nucleus, which encapsulate the cell’s DNA. Though more primitive than eukaryotes, prokaryotic bacteria are the most diverse and abundant group of organisms on Earth-we humans are literally covered in prokaryotes, inside and out.
