Mitosis

        Mitosis is very interesting. Why? Because it helps you grow! It duplicates the cell in a process, and this process has stages. Very interesting. Now, for all those people out there that are short (I feel you, I'm one of them), I'm pretty sure you're wondering why you're short. Maybe your cells aren't duplicating properly? Or that the process of mitosis in your body just works plain slow? Maybe. Maybe not. I don't really know, but I'll find out later.
        Now, one thing you need to remember is that mitosis is not the only type of cell division. It's one of the types, sure, but not the only one. The other one is called meiosis. And no, that's not the same thing. It's quite different. S o if you go out saying that mitosis is the only type of cell division, expect a look that says, What the heck are you talking about? Don't say I didn't warn you.
        Here's a little music video about mitosis.

        Awesome video, huh? And catchy, too. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. Cool, huh? Yeah. So, you know the order, you probably know what they do, now, but what kind of teacher would I be if I let a mere music video teach you guys. Not a very good one. First, I would get a bad grade, and second, that will never get you past your test. Sure, it'll help. But imagine if you suddenly answered every question in rhyme, and singing this song under your breath. Not good. 
        So, I'm going to explain this one by one. First, prophase. Now, as you should know, it is the first step of mitosis. The chromatingenetic material made up of DNAcondenses, which makes the chromosomes (DNA and protein that are found in cells) shorten. The nucleolus breaks down, and the centrosomes, which are a small region of cytoplasm, move apart and begin to build a mitotic spindle.
        Next up, prometaphase. The nuclear membrane breaks down, which allows the spindle to invade the nuclear region. Then the spindle fibers take the chromosomes.  
        Third, metaphase. The spindle fibers pull the
chromosomes  to the central  plate, where they line up.
        Almost done. Anaphase is next. The spindle fibers shorten, and the opposite poles of the cell start to move apart, so that each chromatid of the chromosome is dragged to the opposite of each cell.
        Last step is telophase. The spindle fibers break down. The chromatin also begins to uncoil. Nuclear membranes form around the chromosomes, and the nucleoli begin to reappear.
        Hope this helps you. Remember: Prophase, prometaphase, metaphase, anaphase, and telophase. "P" "P" M" A" T". It's very interesting. Interesting, and it helps us grow. Cool, huh? If you want websites, look down. If you want to learn more, as always, go to SuperSara's and youngro-jalenguy's blog. I put the links below. I just figured out how to do it. Now you can actually go to their websites! I hope you like them. And... we have a new kid. I completely forgot to put him in here. Say hello to Kevin! Have a good day, and until next time!

  1. Good job teemy! Over all, you did really good. I liked it alot and maybe next time you could make a little more interesting. Like add fun facts or something. I'll do that too since I just thought of that idea.
