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
