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

    Microorganisms can be classified as fungi, bacteria, protists, prions, archaea, and viruses. They are claimed as non-living. Microorganisms are known to be single-cellular, or unicellular. Unicellular protists are sometimes seen by the human eye, whereas multicellular protists are sometimes microscopic. They live in several places on earth such as inside rocks within theearth's crust, human skin, a cow’s stomach, and sponges that are used to clean dishes.…

    The Endosymbiotic Theory supports the way eukaryotic cells may have developed. Scientist believe that it began by primitive nucleated cell engulfing masses of blue-green photosynthetic prokaryotes. As same of these prokaryotes survive in the cell, they also begin to make food. The two cells begin to share cell function and become symbiotic. The larger cell provides protection for the smaller cell, while the smaller cell generates food.…

    Examples of prokaryotic organisms include Escherichia coli which is a bacterium of which a certain strain can cause food poisoning, but also occurs naturally in the lower intestines of animals. Examples of eukaryotes range from single celled organisms such as yeasts and amoebae to large multicellular organisms such as plants and animals. Overall, a prokaryote is usually defined by what it lacks rather than what it uniquely…

    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.…

    Archaea is the most ancient of the bacteria. They are single celled organisms which don't have a true nuclei, and live in the most extreme environments on earth. Bacteria is the most abundant organisms on earth. Bacteria is also a single celled organism without a true nuclei called a prokaryote. A Protist is both unicellular and eukaryotic, meaning that it is an organism that has only one cell and that cell contains a nucleus.…

    There are many similarities among Eukaryotes but what must be stressed is that these similarities are broad generalizations and often make oversimplifications in the minutia. As previously mentioned, the broadest and most unifying aspect of eukaryotes is that they have a variety of internal membrane-bound structures called organelles and a cytoskeleton. Membrane-bound organelles especially include the nucleus, which contains the cell’s genetic material is enclosed by the nuclear envelope. Eukaryotic cells also contain other…

    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…

    This source is important because it tells people or explains to them so important information and it also will help me answer basic questions about bacteria. Bacteria are the most abundant forms of life and a bacterium has a whip like thread (flagellum) that is used for swimming. “Also a bacterium has a cell wall for a tough protection, a cell membrane controls which substance enters or leaves the cell, and cytoplasm contains chemicals that help work, grow, and divide”( Kindersley). This is important because it tells what a bacterium has and what it uses it for which will help me explain some pictures of bacteria and what part of the bacteria is what. : “Pea and bean plants such as soybeans use bacteria called Rhizobium which convert nitrogen straight into amino acids” (Kindersley).…

    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.…
