The terms ‘eukaryote’ and ‘prokaryote’ were introduced Edouard Chatton in 1925 (Chatton, 1925, cited in Sapp, 2005). Eukaryotes, according to the online Oxford Dictionaries is a cell in which DNA is arranged in chromosomes that are “contained within a distinct nucleus”. The name prokaryotes is also defined by the Oxford dictionary as an organism that does not contain a ‘distinct nucleus with a membrane’. These two terms highlighted a very important difference between the two cells; eukaryotic cells had a true nucleus surrounded by a membrane but the prokaryotes did not. The following essay seeks to compare and contrast typical prokaryotic cells to typical eukaryotic cells.
Cells can be organised into three domains as stated by Embley and Williams (2015): Bacteria, Archaea and eukaryotes (Eukarya). This is based on the findings of Carl Woesse, who in 1985, discovered three domains in which all cellular life on Earth can be sorted using their ribosomal RNA sequencing. Woesse introduced the domains as Bacteria, Eukarya and Archaea as a basis for a more accurate form of classification as opposed to the five-kingdom taxonomy (Woesse et al. 1990). From a Last Universal Common Ancestor, the Bacteria and the Eukaryotes were thought to have evolved separately. From the Eukarya branch, Archaea branches out. We can use this to make the assumption that all life arose from said LUCA, Archaea are more closely related to Eukaryotes than they are to Bacteria, although morphologically,
