THE CELLULAR ORGANELLULAR LIMERICKAL RAP By ' Doc Henry Dr. Timothy L. Henry Biology Professor University of Texas At Arlington ORGANELLES Organelles rarely fell to organize every cell. Cells organize into tissues very well. Organs make up systems that become us organisms. In organisms like you and me, organelles are the key. All our chemical reactions, without thought or distractions occur inside our cells organelles. CYTOSKELETON The cellular cytoskeleton is like its name. It gives the cell some structure, like a frame. Now its basic elements, Microtubules & microfilaments Are similar, but are not quite the same. While filaments stay in a groove, tubules like to move. VESICLES (LYSOSOMES) Lysosomes are the stomachs of the cell. They digest amino acids very well. If their digestive enzymes leak, things would soon be very bleak. Oxygen deprivations a d**h knell. Endocytosis brings some stuff inside. Like triglycerides & polypeptides. Lysozymes help break them down, then the cell turns right around, to synthesize whatever it decides. (PEROXISOMES) Peroxisomes will take a toxic compound, and with catalases break a poison down. But what is left inside...is hydrogen peroxide, and that can break an organism down. Peroxisomes have peroxidase, to stop hydrogen peroxide in its place. And that is what is meant by an anti-oxidant, so cellular degeneration is denied. (VACUOLES) Like other somes, animal vacuoles are small. Some may not contain much of anything at all. Special hydrolysers, and stored food appetizers, are utilized when a cell makes a call. Good things not saved to eat, vacuoles secrete. What waste they will not keep, vacuoles excrete. RER & SER Endoplasmic reticula come in twos. The one without the ribosomes is smooth. The other has the stuff, and so they call it rough. Protein synthesis is what theyre meant to do. The rough one is for protein modification for reactions like protein transformation are needed at all times, so they change into enzymes for the entire organisms regulation. Smooth ER is just for this: lipid & carbohydrate synthesis. NUCLEUS & NUCLEOLUS A eukaryote nucleus has an envelope membrane surrounding chromosomes of DNA. And theres this other thing, a nucleolus by name that produces ribosomal RNA. Chromosomes used for cellular regulation, use Ribosomes in protein generation. GOLGI BODY The Golgi apparatus packages things, like enzymes & other kinds of proteins. Here vesicles are needed, so stuff can be secreted by Exocytosis via cellular membranes. MITOCHONDRIA Mitochondria, the cellular power source, help proteins and things to run their course. The membrane is double walled, so a process that is called the Krebs cycle can make energy, that is stored as ATP. CHLOROPLASTS Green machines called chloroplasts are definitively one of natures blasts. They use the energy of the Sun, and with water and dioxide of hydrogen, a**emble sugars by doing this: the process of photosynthesis.
