  • Cell Structure and Functions Check us out at This BioCoach module is designed to help you review cell structure. You will find information about the structure of prokaryotic cells and the structure of eukaryotic cells, with a focus on the latter. Animations and interactive activities will enrich your review experience in a dynamic way. This module is designed to be a supplement to, but not a replacement for, your textbook and classroom notes. You can test your understanding of morphology and function of the key structural components described by using the Self-Quiz at the end of the module The common features of prokaryotic and eukaryotic cells are: 1. DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes 2. Plasma membrane, a phospholipid bilayer with proteins that separates the cell from the surrounding environment and functions as a selective barrier for the import and export of materials 3. Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particulates suspended in it 4. Ribosomes, the organelles on which protein synthesis takes place

  • Cell Nucleus and DNA (By Jon C, Mallory L and Clara L) Mr. Luciani PLEASE READ! For some reason when we uploaded this video the music track got louder. We can't edit it because our video editor (Clara) is busy after school and we don't have the file. Furthermore, the voice of the video sped up when we uploaded it. It was around 1:28 before uploading, now its 1:24. Hope you understand! PS: here's is the script if you can't follow along: When looking at cells under a microscope, you might have wondered or thought about the large black spot in the centre of the cell. That black spot is if fact, the cell nucleus. This is Cell Nucleus and DNA in plain English. Lets start with the nucleus, the largest organelle in a cell. Its presence can be used to tell the difference between eukaryotes (cells with a define nucleus) and prokaryotes (cells without an defined nucleus). The nucleus acts like the "brain" and command center of a eukaryotic cell. Placed close to the middle of all the cytoplasms, it can send out information to other cell parts more efficiently. It is also placed in the center since the nucleus is a vital part of the cell, thus meaning that when under attack, most viruses go directly for the nucleus. If a cell does not have a nucleus, the DNA should be floating around in the area called the nucleoid.The nucleus also controls eating, movement, and reproduction. Pretty much anything that happens inside the cell, the nucleus knows about. Wait, Hold it.... 'What is DNA?' you might ask. Well, DNA stands for deoxyribonucleic ...

  • Binary Fission In a Bacterial cell Check us out at The bacterial cell is surrounded by a lipid membrane, or cell membrane, which encloses the contents of the cell and acts as a barrier to hold nutrients, proteins and other essential components of the cytoplasm within the cell. As they are prokaryotes, bacteria do not tend to have membrane-bound organelles in their cytoplasm and thus contain few large intracellular structures. They consequently lack a nucleus, mitochondria, chloroplasts and the other organelles present in eukaryotic cells, such as the Golgi apparatus and endoplasmic reticulum.Bacteria were once seen as simple bags of cytoplasm, but elements such as prokaryotic cytoskeleton,and the localization of proteins to specific locations within the cytoplasm have been found to show levels of complexity. These subcellular compartments have been called "bacterial hyperstructures". Micro-compartments such as carboxysome provides a further level of organization, which are compartments within bacteria that are surrounded by polyhedral protein shells, rather than by lipid membranes.These "polyhedral organelles" localize and compartmentalize bacterial metabolism, a function performed by the membrane-bound organelles in eukaryotes. Many important biochemical reactions, such as energy generation, occur by concentration gradients across membranes, a potential difference also found in a battery. The general lack of internal membranes in bacteria means reactions such as electron transport occur ...

  • Chromosome differences between eukaryotes and prokaryotes The 5 main differences are: Location: eurkaryotes chromosomes located in mitochondria and nucleus whereas prokaryotes located in the nucleoid region Number of base pairs: eukaryotes around 3.2 billion, prokyaryotes around 4 million Number of genes: eukaryotes around 25000 and prokaryotes around 5000 What kind of genome: eurkaryotes are diploid and prokaryotes are haploid also, there are telomeres at the ends of eukaryote chromosomes. Also, the ribosomes on a prokaryote is only 70s with 50s and 30s whereas the eukaryote is 80s with 40s and 60s.
  • The Cellular Song Lyrics, Vocals and Animation by Uno de los Reyes To the tune of "Hoedown" from "Whose Line is it Anyway" PROKARYOTE (singing) I am a prokaryote, a simple little cell I don't have much inside me, it does me very well A cell membrane, some ribosomes, and scattered DNA Just the bare necessities, and I do okay. (Well, sometimes I have a flagellum, but otherwise I'm quite simple. Really! My DNA is in a section called the nucleoid. My body parts all float around in a liquid called the cytoplasm, but besides that I'm quite simple. Really! Oh, wait, did I say that already? Uh, let me check my script. Hmm. Oh, yes, yes. It's that important. Just remember that I'm really simple. But despite this, I am capable of withstanding extreme conditions, which is quite an advantage to me as compared to my cousin, the eukaryote. Speaking of whom, here he comes! Hi cousin!) EUKARYOTE (Hiya!) (singing) I am the eukaryote, the much more knotty one I've got all my organelles, which makes me quite fun They have many functions, but the list is really long, Oh well, to find out, you'll have to wait for the next song! PROKARYOTE Oy.
