![]() ![]() These are basically cells with simple configuration, orientation and mechanism. But even today they are a substantial part of human life. As the name suggests, the evolution of prokaryotic cells is at least 3.5 billion years old. The term prokaryotic has arisen from Greekwords “Pro” and “Karyon” ( Pro: ancient/primitive karyon: nut/nucleus). Organelles are membrane bound and are specific in function. Organelles are not membrane bound, if present any. Transcription occurs in nucleus and translation in cytosol. (conjugation, transformation, transduction) Well-defined nucleus is absent, rather 'nucleoid' is present which is an open region containing DNA.Ī well-defined nucleus is present enclosed within nuclear memebrane. Usually cell wall absent, if present (plant cells and fungus), comprises of cellulose (polysaccharide). Content: Prokaryotic cells Vs Eukaryotic cellsĬell wall present, comprise of peptidoglycan or mucopeptide (polysaccharide). In the following content, we will discuss the general difference between these two types of cells with the help of a comparison chart along with a brief description of their respective components. Contrarily, the eukaryotic cell has a precisely distinct nucleus to store the genetic material. ![]() The prokaryotic cell lacks the membrane-bound nucleus and thus the genetic material remains scattered in the form of the nucleoid. The prokaryotes are lower organisms that are unicellular whereas the eukaryotes can be unicellular (amoeba) or can be multicellular (higher organisms like plants, animals, fungi etc). ![]()
