Life Is Life

       Life is life. Tables are tables. Paper is paper. Cells are cells. Oh hi there! I was just... actually I really don't know what I was doing. Well while I was saying random things, I said what we are going to be learning about. That's right we're gonna talk about paper tables! Just kidding we are going to be cell life, or the cell cycle. There are two major stages in the cell cycle. And they are mitosis and interphase. Mitosis has prophase, metaphase, anaphase, and telophase. Interphase has G1, S, and G2 phases. 


       

     Before a cell can go through cell division, it needs to prepare itself by doubling everything it has. All that happens through interphase.  If you think about it, interphase is basically a copying machine! 



 

        Now on to mitosis. There are 4 main stages in mitosis, and they are prophase, metaphase, anaphase, and telophase. Prophase is the first stage in mitosis. During this stage, it packages DNA into chromosomes. Also, the spindle fibers go to different sides of the cell. 




       The next stage is metaphase. This is when the chromosomes line up in the center of the cell and the spindle fibers spread out to where  one chromosome in on one spindle fiber thread. So everything is exact. Talk about perfectionists! But, it has to be perfect or else the mitosis won't work. 





      The third phase is anaphase. In this phase, the spindle fibers pull the chromosomes apart and half of the chromosome (which is called the chromotid) is pulled to different sides of the cell. 




       The last stage of mitosis is called telophase. In telophase, the DNA spreads out and 2 nuclei are formed. That happens in both animal and plant cells. But there is one part in telophase that is different in a plant cell. In animal cells, the cell membrane pinches to form 2 new daughter cells. In plant cells, a new cell wall forms in between the 2 new daughter cells. So not much of a difference, but it's still a little!




      Now this part next part isn't part of mitosis, but it is part of cell division. Kinda like interphase. This part is called cytokinesis. Isn't that a cool word? Anyways, cytokinesis is the last part of cell division. In this part, the 2 different cell membranes form and the cells separate from each other. Now you have 2 new cells!! YAY!

Well that's all for this blog! Bye everyone!! Science Fun:)
