Prokaryotic vs Eukaryotic Cells
Eukaryotic vs. Prokaryotic cells
Prompt: Describe the similarities and differences between Prokaryotic and Eukaryotic cells. All organisms are made of cells. The cell is the simplest collection of matter that can be alive. Cells are the basic structural and functional units of every organism. Cells fall into two distinct types: Prokaryotic and Eukaryotic. While Prokaryotic and Eukaryotic cells are similar in that both types of cells are bounded by a plasma membrane, all contain cytosol, and all have chromosomes and ribosomes; they differ in the location of their DNA, organelles in the cytoplasm, and their size. All cells share certain basic features. They are bounded by a selective barrier known as the plasma membrane. All cells contain cytosol which is a semifluid, jelly-like substance. Also all cells have chromosomes and ribosomes. Chromosomes carry genes in the form of DNA. Ribosomes are tiny complexes that make proteins according to instructions from the genes. An important difference between Prokaryotic and Eukaryotic cells is the location of their DNA. In a Eukaryotic cell, most of the DNA is found in the Nucleus. The Nucleus contains three distinct parts, the Nuclear envelope, the Nucleolus, and Chromatin. The Nuclear envelope is a double membrane. Also pore complexes connect the nucleus to the Endoplasmic Reticulum. The Nucleolus doesn’t have a membrane structure. It serves in the production of ribosomes. Lastly, Chromatin is material consisting of DNA and proteins. In a Prokaryotic cell, the DNA is concentrated in the Nucleoid. The Nucleoid is also not membrane-enclosed. The interior of either type of cell is called the cytoplasm. Within the cytoplasm of a eukaryotic cell, a variety of organelles of specialized form and function are found. In a prokaryotic cell, however, these membrane-bounded structures are absent. Eukaryotic cells are generally much larger than Prokaryotic cells. They have internal membranes that compartmentalize their

    But not all cells are alike. Cells come in many shapes and sizes and perform various functions, depending on where they are found (Infographic 3.2). Moreover, they fall into two fundamentally different categories: prokaryotic or eukaryotic. Prokaryotic cells are relatively small and lack internal membrane-bound compartments, called organelles. Eukaryotic cells, by contrast, are much larger and contain many such organelles.…

    There are also many differences between the two cells, the most obvious being the size of the two and with the difference in complexity. The most distinct difference is that Eukaryotic cells have a true nucleus bound by a double membrane. Prokaryotic cells do not have one. Another difference is despite the fact they both have DNA, eukaryotic DNA is complexed with proteins called histones and is organized into chromosomes. Prokarytoic DNA is naked, meaning it has not histones associated with it, and it is not…

    Most notably the lack of a nucleus in prokaryotes and membrane bound organelles. The DNA of prokaryotes floats freely around the cell; the DNA of eukaryotes is held within its nucleus. The organelles of eukaryotes allow them to exhibit much higher levels of intracellular division of labour than is possible in prokaryotic cells. Another physical difference is the size of both cells. A prokaryote is only 0.5-5 μm, whilst Eukaryotes are on average 10 times bigger at up to 40μm. Mitochondria are absent from Prokaryotes, yet found in Eukaryotes, as are chloroplasts (though chloroplasts are not found in animal cells). One difference as far as existence is concerned, is that prokaryotes are believed to be the first form of life around 3.5 billion years ago. Eukaryotes are much younger, and believed to have existed around 1.5 billion years ago when the cells developed a nucleus- multicellular organisms are younger still at 0.5 billion years…

    There are two different types of cells, there are prokaryotes and eukaryotes. Within eukaryotes there are different structures and similar structures. For example; in a plant cell they have a nucleus, mitochondria an ER, and a Golgi body. These are the same as animal cells; however they differ because plants cells have a cellulose cell wall, chloroplasts, large central vacuole and they use starch for storage whereas an animal cell has lysosomes, rough ER, smooth ER and ribosomes. Eukaryotes differ from prokaryotes because prokaryotes have no nucleus, they just have a loop of DNA and they also have no membrane-bound organelles. Prokaryotes also have a cell wall, along with a slime capsule, flagellae and plasmids.…
