Prokaryotic and Eukaryotic share similar characteristics yet have some different properties that make each unique. Both of these cells have a cell membrane, ribosomes, cell wall, and cytoplasm (Pommerville, 2014, p. 71). DNA is another similarity both cells share a commonality with; however, their DNA is structurally different. The significant difference between these two cells is that prokaryotes have no nucleus and eukaryotes do. Prokaryotes are bacteria and archaea species, whereas eukaryotes organisms include algae, protozoa, fungi, plants, and animals. Additionally, eukaryotes have organelles and multiple and linear DNA, whereas prokaryotes have circular, single DNA and have no membrane-bound organelles (Pommerville, 2014, p. 71). Eukaryotes have organelles, like mitochondria and chloroplasts and prokaryotes do not have organelles. Prokaryotes contain polysaccharide peptidoglycan, and eukaryotes do not, which is significant as antibiotics act against peptidoglycan and will not affect human eukaryotic cells (Tortora, Funke, & Case, 2013, p. …show more content…
Prokaryotes are small and simple, unicellular, and cells have a sticky capsule. Prokaryotic cells have three basic shapes consisting of Cocci - spherical, Bacilli – rod-shaped, and Spirochaete – spiral-shaped. Although some bacterial species will have an appendage, some with branching filaments, while others such as the archaeal species, will be square or star-shaped (Pommerville, 2014, p. 106). Eukaryotes are larger and more complex, can be unicellular, similar to the prokaryote, and also multi-cellular. The cytoskeleton is exclusive to eukaryotic cells and provides a layer of protein filaments around the cell membrane (University of California Museum of Paleontology, 1994). This layer surrounds the cell giving eukaryotes their

Prokaryotes Vs Eukaryotes

whether a cell is a prokaryote or eukaryote is by seeing if it has a nucleus. A prokaryote does not have a nucleus, which a eukaryotic does. Another way is to see if their are membrane bound organelles. Prokaryotes do not have membrane bound organelles, while eukaryotes. Lasty, you can tell by looking at the size and complexity. Prokaryotes are smaller and less complex than eukaryotes. Scientists believe that single celled eukaryotes are more complex than multi celled eukaryotes because they do so…

This genetic material is passed on to offspring and often changes slightly over time, that is, it evolves! 4 4/10/2011 Cells – Two Basic Types! • • Prokaryote (=before kernel) – are cells without a defined nucleus; genetic material is not contained within a membrane. Eukaryote (=with kernel) – are cells that have a defined nucleus where genetic material is kept. Notes: Biologists recognize that organisms use one of two types of cells. It is believed that the…

Ribosomes(location of protein synthesis) *Prokaryotic= DNA, Ribosomes, Cytoplasm (can’t do many things at once) DNA is in a circle shape- they are structurally simpler than Eukaryote: No membrane bound organelles, NO nucleus, DNA in an unbound nucleus thus being Nucleoid, Cytoplasm bound by the plasma membrane. *Eukaryote= Subdivided to perform multiple tasks: have a true nucleus *DNA (deoxyribonucleic acid)= the chromosomes have almost all of the cell’s genetic material. The division of cells…

Organisms Are Bacteria, Achaea, or Eukaryotes - Biologists recognized two types of cells 1) prokaryotes 2) eukaryotes - The simpler type is characteristic of bacteria (Prokaryotes) and the more complex type characteristic of plants, animals, fungi, algae, and protozoa (eukaryotes) - The main distinction between prokaryotes vs. eukaryotes is the membrane-bound nucleus that eukaryotic cells have - Recently there has been a changing view of prokaryotes. The term prokaryote is unsatisfactory in describing…
