Mitosis
Mitosis contains five steps that it must complete in order for the cell to divide. They is interphase, prophase, metaphase, anaphase, and telophase.
- Interphase prepares the cell to divide and the DNA is duplicated. Some organelles are also manufactured and the cell continues to grow. If the stage was non existent when the cell divides into two the other cell would not have any DNA or any organelles to survive, therefore making the whole rest of the process worthless.
- Prophase is when the chromosomes condense and some spindle fibers form. The nuclear membrane disappears as well as the nucleolus. The nuclear envelope begins to break down and the spindle fibers start extending to both poles of the cell. Centrioles are also being produced in the stage, and chromatin becomes chromosomes so both cells will have the right amount of chromosomes can be distributed equally when the cell splits.
- Metaphase is the chromosomes lining up in the center of the cell, the spindle fibers also attach themselves to the centromere of the chromosomes this causes tension in the middle of the cell. It is like a tug of war between two people with the exact same strength and this leads to the destruction of cyclin that is in the cell. Cyclin is protein that is associated with the cell cycle and is believed to initiate certain processes of mitosis.
- Anaphase is the process of when sister chromatids separate to opposite sides of the cell. The spindle fibers shorten up and the kinetochores separate. The kinetochores are the substances that the spindle fibers attach to the chromatid. The kinetochores are usually located at or close by to the centromere. In anaphase nuclei begin to form within the cell as well.
- Telophase has new nuclei from and the chromosomes begin to unfold and then go back into chromatin from preparing for interphase (stage one of mitosis). The daughter chromosomes arrive at the poles and the spindle fibers disappear. The nuclear membrane also begins to reform at both ends of the cell. the kinetochores are dissmissed as they are not needed anymore

Cytokinesis
- Animal Cells cytokinesis in an animal cell is when the cell membrane is brought inward by a ring of protein like substances until the cytoplasm is squeezed into two almost equal parts, which means that the two cells will get an even amount of cytoplasm. The main function is that the single cell is pinched to make two daughter cells.
- Plant Cells cytokinesis within a plant cell is when a call plate forms. a cell plate is a wall like structure that splits the cell in half. Later the cell will split where the cell plate is creating two daughter cells.
- The difference The only difference between cytokinesis within a plant cell and within an animal cell is that in a plant cell a wall like structure called a cell plate that splits apart the cell into two sides that will soon be two daughter cells. In an animal cell the cell is simply pinched down the center that will soon be two different daughter cells.
