An Essay on the comparison and contrast of the differences between prokaryotic and eukaryotic cells. All organisms are either categorized as a prokaryote or a eukaryote. These two groups are fundamentally different. Prokaryotes are organisms with prokaryotic cells and eukaryotes are organisms with eukaryotic cells. The terms prokaryotes and eukaryotes are in reference to where the DNA is actually housed. Eukaryotic cells are found within organism which are single-celled or multi-celled and contain membrane-bound organelles such as a nucleus which contains genetic information that 's is enclosed within a nuclear envelope meaning eukaryotes have a true nuclei whereas prokaryotic cells are found in organisms that cannot

The cytoplasm is loaded with small structures called ribosomes, which can be used to translate RNA to protein, DNA replication, translation, and movement. Prokaryotic cells are less complex than eukaryotic cells but are able to achieve the equivalent process in function, for example, DNA transcription and Replication occurs within the nucleoid of a prokaryotic cell but the translation occurs within the ribosomes which float around freely in the cytoplasm. Whereas in eukaryotic cells, the transcription process occurs within its nucleus. Both prokaryotic eukaryotic ribosomes are made up of RNA and proteins but the subunits are dissimilar in sizes.Both prokaryotic and eukaryotic have DNA as their genetic material. In regards to the metabolism between prokaryotic and eukaryotic cells, both use the same basic metabolic pathway but prokaryotic cells tend to have a variation of different pathways and materials due to the vast amount of different enzymes.this has allowed prokaryotes to canonize and survive in environments that eukaryotes couldn 't survive …show more content…
Flagella and cilia are usually found in eukaryotic cells whereas, in prokaryotic cells flagella, endo flagella and pili can be found. Flagella is usually found within prokaryotic cells and eukaryotic cells, but the pattern and structure are very dissimilar when looking closely, eukaryotic cells have one or more microscopic long whip-like appendage that drives the movement of the flagella back and forth . The flagella is approximately 200mn in diameter and are attached to the cell by the basal body and the movement is influenced by the energy from the adenosine triphosphate (ATP). The flagella in eukaryotic cells have microtubules which consist of protein tubulins and are intracellular, whereas Bacterial flagella are helical structures which contain protein flagellin. The basal body is enclosed within a cell envelope.The movement of the flagellum differs from a eukaryotic cell but is also known to be driven my motor proteins that swing the flagella in a clockwise or counter-clockwise direction. The movement of the flagella in prokaryotes is influenced by the energy from the ion gradient or the proton-motive force. Prokaryotic cells contain a cytoskeleton which contains similar proteins to actinc and fiaments of a eukaryotic cell. The prokaryotic flagellum is approximately 20nm in diameter compared to the 200nm in diameter in the eukaryotic flagellum.
