Get Access Differences between prokaryote and eukaryote cells Essay Sample The cell is the basic functioning unit of organisms in which chemical reactions take place. These reactions involve an energy release needed to support life and build structures. The cell consists of membrane bound organelles, which are responsible for the division of labour.

Speaking in simple cell biology words, prokaryotes are primitive, simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes, which are advanced and complex organisms having membrane bound cell organelles.

Seemingly simple in structure and markedly different from eukaryote and protist organisms, prokaryotic cells are believed to have been amongst the first on the Earth and very well may out-survive all other organisms.

Prokaryotic cells essay

Examples of prokaryotes are bacteria and archaea and eukaryotes include fungi, animal and plant Prokaryotic cells essay. One of the main differentiating points between the two is the presence or absence of membrane enclosed nuclear body.

In prokaryotes, it lacks outer membrane covering and nucleolus, whereas nucleolus is present and a double Prokaryotic cells essay membrane surrounds the nuclear body in eukaryotes.

Referred to as cell nucleus in eukaryotes, such an organelle is called nucleoid in prokaryotes. The nuclear body houses the chromosome in both prokaryotes and eukaryotes.

Single in number and circular in shape, the chromosome in prokaryotes is made up of Deoxyribonucleic Acid DNA and proteins whilst in eukaryotes, it is usually more than two in number, and composed of DNA, histone and other proteins.

In terms of ribosomes prokaryotes consist of 70S type, and the two subunits are 50S and 30S. Ribosome in eukaryotes is of 80S type, and the two comprising subunits are 60S and a 40S.

Since the cell size in prokaryotes is relatively smaller to that of the eukaryotes, the organelles like mitochondria, golgi bodies, endoplasmic reticulum and chloroplast are absent in the small-sized prokaryotic cells whilst Eukaryotic cells house all these membrane bound organelles inside the cell.

Cell division in prokaryotes is simple, and occurs by binary fission method.

Over here, the parent cell haploid cell divides into two equal daughter cells. Eukaryotes have diploid cell that divides first by mitosis, and further into two haploid ones by meiosis.

The resulting haploid gametes fuse to give a diploid cell. Most eukaryotic cells are uniquely suited to their own particular environmental niche and rarely grows out of it, but prokaryotes i.

A major difference in chemical composition between prokaryotic and eukaryotic cells is that eukaryotes have sterols in their membranes e.

In prokaryotic cells the enzymes, topoisomerases, that control topological changes in DNA architecture are different from their eukaryotic counterparts act on linear Chromosomes.

The cytoplasm of prokaryotes is densely packed with ribosomes that are not associated with a membranous structure ie endoplasmic reticulum whilst in eukaryotic cells the ribosomes can either be free lying or bound to the endoplasmic reticulum.

Prokaryotes maintain their DNA in a supercoiled state by the combined action of two enzymes that can alter the linking number of DNA without changing its primary structure. These enzymes are called DNA topoisomerases.

It is the combined action of these two opposing enzymes that allows bacteria to maintain a delicate balance and proper super helical density of the chromosome required for replication, repair, recombination and gene function.The similarities and differences between prokaryotic and eukaryotic cells Prokarytotic cells Eukaryotic cells Similarities Nuc Offers; Fair Use Policy; Help Centre If you are the original writer of this essay and no longer wish to have the essay published on the UK Essays website then please click on the link below to request removal.
