Prokaryotes Vs Eukaryotes Essay

Improved Essays
Some cells are uncomplicated, but others are complex with internal structures called organelles. These cells can be put into two categories which are the prokaryotes and the eukaryotes, and they have many differences and similarities. The prokaryotes derive from prokaryotic cells whose fossils have been in existence for over 3.8 billion years, which mean they have learned to adjust to the earth’s environments more than any other life form. Prokaryotes are the bacteria and their close relatives, of which have few internal parts. The prokaryotes are a assorted body of fundamental one-celled organisms that are divided into two major groups: the Archaea and the Eubaceria. Units of the Archaea can be described as inhabitants of drastically hostile surrondings. The Eubacteria, are pervasive living agreeably in most enviornments. Every breath carries some bacterial spores, and almost every surface holds them. When it comes to the intestines, some are helpful, giving nutrients, vitamins and absorbing water in return for space. Some prokaryotes are our enemies, causing diseases and …show more content…
Eukaryotic cells come in a variation of forms. Some can be single-celled organisms that are generally bigger than prokaryotes. Human adults are made up of about 100 trillion cells of over 200 distinctive types. Internally, eukaryotic cells are considerably more complex than prokaryotic cells. The prokaryotes as well as the eukaryotic cells are enclosed in a spoongy cell membrane, but unlike prokaryotes, eukaryotes also have membranes within the cell that enclose tiny intracellular compartments where essential functions and processes can occur in isolation from the rest of the cell. The inside of the eukaryotic cell is a highly structured and organized, consisting of eukaryotic cells which externally may be bare or have cell walls, flagella, or cilia. In addition to that, they have internal

    These organisms fit in one of the three domains: Archaea, Bacteria, and Eukarya. Archaea and Bacteria fall under the category Prokaryotic. Of the organisms studied Bacteria falls under the Prokaryotes in the Bacteria domain. Bacteria tend to be unicellular, they have a cell wall but lack a nucleus as well as other membrane organelles, and they contain a nucleoid where all the chromosomes are located. Their mode of locomotion is thru…

    Support the Endosymbiotic Theory Gianna Melendez Chamberlain College of Nursing Support the Endosymbiotic Theory The endosymbiotic theory proposes that eukaryotes formed from the union of small aerobic prokaryotes with larger anaerobic prokaryotes, which form organelles. The smaller prokaryotes were not destroyed by the larger cells, but instead became internal parasites that remained surrounded by a vesicular membrane of the host. The theory proposed that mitochondria are the result of endocytosis of aerobic bacteria and chloroplasts are the result of endocytosis of photosynthetic bacteria.…

    Although these two cells share a lot of similarities there are also many differences between the common prokaryotic and eukaryotic cells, however more specifically I will be exploring how the structure relates to the function of an animal cell and a non-photosynthetic prokaryotic cell, and it is explained that, “analysing a biological structure gives us clues about what it does and how it works” (Campbell et al: 2014, p.52). The structure and the function of a cell generally aren’t one without the other, and all biological structures have evolved through time to fit the purpose in which they are needed as they interact with the environment. The way they gain their energy is through other consumers as the energy that they have is used more…

    This essay focuses on the characteristics and functions of a prokaryote and a eukaryote. Prokaryotes, unicellular cells, are much smaller compared to eukaryotes, often multicellular cells. Viruses are much smaller than prokaryotes, however, they aren’t considered as cells. Both viruses and prokaryotes don’t have numerous amounts of organelles in their cells. Prokaryotes only contain certain ones, which help them survive, for example; they have mitochondria, flagella and Nucleoid.…

    Prokaryote are unicellular organisms that are only visible under microscopes. Unlike Eukaryotic cells, Prokaryote cells do not contain a nucleus, chloroplasts and mitochondria. They are a very significant decomposer that reproduces asexually through mitosis. Some Prokaryote can eat through photosynthesis, while some of them absorb food they are in or on.…

    Eubacteria best live in moderate temperatures, low salts and where there is a plethora of sunlight or organic compounds (Ladiges, 2010). The main differentiating structure of eubacteria is that it has peptidoglycan in its cell walls, has one RNA polymerase and has the ability to form spores that can live many years but remain inactive until its environment is just right for it to activate itself. They are similar to eukaryotes in that they also have ester linked lipids, may photosynthesise using chlorophyll and their DNA are both negatively coiled. Archaebacteria uses ether linked lipids, have membranes that enclose lipids with hydrocarbons and survive extreme conditions for example hot springs or extreme pH (Ladiges, 2010 ). Both eubacteria and archaebacteria live up to the prokaryote name in that they both have no cell nucleus, their ecological roles are similar, produce a-sexually and are similar in size and shape on a cellular level.…

    Simpler than eukaryotes, but complex compared to bacterial cells, Archaea are single celled microorganisms that are similar to bacteria in size and simplicity of structure but more closely related to Eukaryotes when it comes to molecular organization. They are believed to have evolved before Eukarya and after Bacteria which can be proved by microfossils traces, biomarkers, and more. Archaea at first seemed very similar to Bacteria, and many were categorized as such. Only later was the new domain Archaea suggested. Just like Eukaryotes, Archaea have a nucleus and membrane bound organelles in addition to which they also share many similar features and pathways with humans on the molecular level, such as the enzymes used in transcription and…

    Some of these organelles include the nucleus, which holds the cells DNA, mitochondria, which produce ATP from glucose and oxygen, known as cellular respiration, and the golgi body which packages and processes different substances leaving the cell. Prokaryotic cells are the simpler of the two cells and are single celled organisms, such as bacteria, that don’t contain organelles.…
