Prokaryotes And Eukaryotes Similarities

Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually spread in the cytoplasm. In eukaryotic cells the chromosomes remain together inside the nucleus and there is a clear nuclear membrane that is surrounding the nucleus.

Bacteria are prokaryotic, and if you were to observe the two cells under a light microscope, you could distinguish their differences. The biggest distinguishment you can make while carefully observing the two cells, is the lack of a nucleus in a prokaryotic cell as compared to a eukaryotic. Prokaryotes also lack any membrane-bound organelles.

Well prokaryote is the name given to organisms that are made up from cells that lack a cell nucleus or cells that lack any membrane-encased organelles (a specialized subunit within a cell). In lamens terms, in prokaryotes, the DNA is not bound or held together inside a nucleus. Prokaryotes also only have a single loop DNA. Last but not least prokaryotes are divided into groups or domains but more about that in a minute.

Bacteria and Archaea are prokaryotic, which are mostly single-celled incomplex microorganisms. Both Bacteria and Archaea have a variety of prokaryotes classified in multiple kingdoms (Reece, et al., Campbell Biology, 2014). There are a number of scientists who believe that Archaea cells may be the precursor to Eukaryotic cells and that they have more in common with Eukaryotes than Prokaryotes (Madigan, Martinko, & Dunlap, 2009).

Eukaryotes and bacteria cells both have the common cell structure of flagella. Flagella is considered a protein. The purpose of the flagella is to help the cell move. Eukaryotes have a different movement type than bacteria. Eukaryotes move in form of an s-shape. Bacterial cells move like helicopter blades (rotor type movement). The flagellum of the bacterial cell are a lot thinner the eukaryote due to the size of the cell.

eukaryotic cells cell type is usually multicellular while prokaryotic cell is usually unicellular, eukaryotic cell true membrane bound nucleus is present, prokaryotic cell's true bound nucleus is absent. examples of a eukaryotic cell are plants and animals. prokaryotic cells's examples are bacteria and archaea. eukaryotic cells genetic recombination is meiosis & fusion of gametes, prokaryotic cells genetic recombination is partial, undirectional transfers DNA, eukaryotic cells lysosomes and peroxisomes are present while prokaryotic cell lysosomes and peroxisomes are absent, eukaryotic cells microtubules are present, prokaryotic cells microtubules are absent, eukaryotic cell endoplasmic reticulum is present, prokaryotic cell endoplasmic reticulum is absent and eukaryotic cells cytoskeleton is present while prokaryotic cells cytoskeleton may be

The eukaryotic cell and prokaryotic cells are alike in many ways, Some ways they are alike is that they have DNA as their genetic material , membrane bound, have ribosomes, similar basic metabolism, and amazingly diverse in forms. This is the twin like feature that they have. The eukaryotic cell and prokaryotic cells differ in way to

Prokaryotes have a cell wall but are only made from cellulose. Prokaryotes have no nucleus. Prokaryotic cells are found in single-celled organisms such as bacteria. The DNA in a prokaryotic cell is in the cytoplasm rather than enclosed thin a nuclear membrane. The two organisms from prokaryotes are bacteria and blue green algae

Their structural similarities are the reasoning behind why one might say that they belong to the prokaryotic domain, being structurally very similar, especially on the first glance. The unique properties will be discussed further later in this essay. SIMILARITIES BETWEEN EUKARYOTES AND ARCHAEA Though structurally, prokaryotic cells seem more similar to archaea than eukaryotic cells, yet when one inspects their DNA, similarities between DNA replication, transcription and translation appear. The DNA polymerase in archaea and eukaryotes are not related to any prokaryotic DNA polymerase, suggesting that these two are of common origin. Other components used in DNA replication are similarly only shared between eukaryotes and archaea (y).

These proteins form a network within eukaryotic cells which assist greatly in maintaining structure. Their major functions include determining the shape of the cell, particularly for those cells without a cell wall, they allow the cell to move without the need for flagella found in prokaryotic cells through a cycle of assembly and disassembly of microtubules and microfilaments, they assist with organelle movement within the cell, and lastly, they are required for the process of cell division by the movement of chromosomes into the new daughter cell, and also to assist with the process of cytokinesis. With regard to eukaryotic multicellularity, the rigidity provided by the cytoskeleton provides the cells with resistance to being distorted, and thus permits anchorage of the cells to extracellular constituents and neighbouring cells which allows the cells to develop cooperative structures, such as tissues (Alberts,

Cell is a wide type of substance that have variations between species and species, for example a plant cell contains a cell wall which is absent in most animal cells. Scientists had been trying to classify all organisms into different groups. Current classification system is the three domains and six kingdoms which the three domain divides organisms based on the ribosomal RNA they contained in the cells. The three domains are Bacteria, Archaea and Eukarya which the first two are made up of prokaryotic cells and Eukarya is made up of eukaryotic cells. This essay will focus on the differences between eukaryotic and prokaryotic cells.

Eukaryotes accord to the taxon Eukarya or Eukaryota. The defining affection that sets eukaryotic beef afar from prokaryotic beef is that they accept membrane-bound organelles, abnormally the nucleus, which contains the abiogenetic material, and is amid by the nuclear envelope. The attendance of a basis gives eukaryotes their designation, which emanates from the Greek εὖ and κάρυον . Eukaryotic beef along accommodate added membrane-bound organelles such as mitochondria and the Golgi apparatus. In additament, plants and algae accommodate chloroplasts. Eukaryotic bacilli may be unicellular, or multicellular. Alone eukaryotes accept abounding kinds of tissue composed of altered corpuscle types.

All species of fungi, plants and animals are formed from eukaryotic cells. The Eukaryote have a true nucleus; their DNA is confined to a definite area within the cell enclosed by a Nuclear envelope. Prokaryotes evolved before eukaryotic cells and their cells do not have a true nucleus. Prokaryote DNA is not enclosed by a membrane.

The origin of eukaryotic cells is considered a milestone in the evolution of life. The most likely sequence for the evolution of eukaryotic cell is structure, multicellularity, and then sexual reproduction. Prokaryotic cells have a simple cell structure and lack a nucleus. The nucleus was the first thing to evolve in a prokaryotic cell. According to a chapter titled, “The Origin and Early History of Life” “the nuclear envelope may have evolved from infoldings of the plasma membrane” which then enclosed the DNA of the cell. Organelles such as mitochondria and chloroplasts then started to develop. Ancestral mitochondrial was a free living prokaryotic cell that was capable of using oxygen to perform cellular respiration and therefore

Although both Archaeal and bacterial cells possess flagella for motility, the composition of each organism’s flagellum is very different. In bacterial cell, the flagellum is composed of a basal body, external protein filaments both are joined together by a third component called the hook.(Bacteria Flagella David Gene Morgan , Shahid Khan). In Archaeal, the protein filament is polymerised, glycosylated and very much thinner. The Archaeal flagellum is believed to be similar to the bacteria IV pilus in structure.(www.uniprot.org/keywords/974).
