In Which I Explain Mitosis and Meiosis

     You are fully aware that in order to be considered life, you must be able to do a few simple processes; those being ordered structure, growing, use of energy, responsiveness, change and adaption, and finally- reproduction.
      That last process is going to be our main focus, specifically the reproduction of cells. In generalization, cells go through a process that allows them to copy and eventually split themselves to make to new cells... and inevitably start the cycle all over again. It goes through the processes of Interphase (centrosomes and nucleus line up on opposing sides of the cell), Prophase (alike pieces of chromosomes connect in the familiar x shape called centromeres with miotic spindles), Prometaphase (centrosomes go to either side and start to attatch and organize the chromosomes), Metaphase (Chromosomes are completely aligned), Anaphase (miotic spindles pull apart the two halves of the centromeres to their respective sides of the cell), Telophase (A divider is put down between the two halves and we begin to see the full splitting of two cells) and Cytokinesis (the process of the complete split into two bodies).

I know how hard that was, so this image is going to show you everything I just said; but it will prove that I didn't even have to type that... Enjoy.



     This little image shows the length of time each of these processes take in order to fully complete the cell cycle.

     With the wordiness aside, we can talk about Meiosis a little bit and what is the difference between the two.  Meiosis has a slightly different process to achieve the same product. But Meiosis happens in life (humans yeh) and mitosis happens in plants (tulips yeh). This image is going to sum this all up nicely and save you some reading.
