The Cell Cycle

     The way that we grow is by cells dividing. The way that cells divide is called mitosis. Cells go through many stages during mitosis. The first stage is interphase. Most of the time cells are in interphase. During interphase, the cell grows to its full size and makes copies of your DNA. Prophase is next. Prophase is when chromatin condenses inside the nucleus and the nuclear membrane starts to break down. Metaphase is when chromosomes start to line up in the center of the cell. During anaphase all the chromosomes break apart and move to each end of the cell. Telophase is when the chromosomes stretch out and a nuclear membrane begins to form at each end of the cell. The last phase is when the cell breaks in two and each cell start to form new cell walls, which is called cytokinesis. 
     After the cell comes apart you now have two new daughter cells. The new cells begin to go back to coping DNA a starts to become prepared to go through mitosis and make new cells. Without mitosis, you would not be able to grow and thrive. This is the main way that animals grow. Other single-celled organisms do not go through mitosis. Single-celled organisms are only made of one cell and don't need to make more.
