Cell Division
II. What is mitosis?The cell begins to form a round shape while the nucleus and chromosomes also start to form, this is the Interphase. Later, the nucleus breaks down releasing the chromosomes and the chromosomes begin to line up in the center of the cell with the help of spindle fibers. This is the Prophase and the Prometaphase. In the Metaphase, spindle fibers begin to split the chromosomes into two halves. In the Anaphase, the chromosomes and spindle fibers move in the opposite direction from the other chromosomes and splits the cell into two identical parts. Cytokinesis turns the two identical cells into the Interphase.

III. What is meiosis?In meiosis, the nucleus breaks down and releases chromosomes. Homologus dyad pairs start to form tetrads in a process called Prophase. The spindle fibers attach themselves to the chromosomes and splits the chromosomes and puts them on different areas opposite to other chromosomes. This is called Metaphase. In the next phase, the Telophase, the cell splits and makes a duplicate identical cell. In the two cells, one cell has a pair of chromosomes while the other cell has a different pair of chromosomes. In meiosis II, the steps are very similar to meiosis I but the difference between the two is that the cells have a different chromosomes in each cell. Meiosis II creates gametes.

IV. Mitosis v. MeiosisThe difference between mitosis and meiosis is that mitosis creates two identical cells while meiosis creates four different cells. There is one distinct division in mitosis while there is two distinct divisions. Mitosis contains all four chromosomes in each cell while meiosis contains two different chromosomes in the four cells. Mitosis only occurs in asexual reproduction and meiosis doesn't occur in asexual reproduction.
