I. What is the Cell Cycle?
A cell is when a cell is in the process to divide itself, in order to make an exact duplicate cell of itself. The cell cycle has 5 different stages. They are Interphase, Prophase, Metaphase, Anaphase and Telophase (cytokenises). Interphase is when the cell doubles in size, grows new organelles, and replicate chromosomes, the second stage is Prophase and thats when the chromosomes condense, centriole pairs separate and move towards the opposite ends of the cell, and formation of the spindle apparatus occurs. The third stage is Metaphase it is the centriole pairs that are at opposite poles of the cell and the chromosomes align at the equatorial plate. While the Anaphase is when the centromeres split, so each chromatid has its own centromere, the sister chromatids are pulled towards opposite poles of the kinetochore fibers shortening. The last stage is Telophase and thats when the spindle disappears, nuclear envelope reforms around each set of chromosomes, the chromosomes uncoil, and then the cytoplasm of the cell divides from two new cells.

III. What is meiosis?Meiosis is a two part Cell Division process in organisms that sexually reproduce, it produces gametes with half the number of chromosomes as the parent cell. There is two parts of Meiosis which is Meiosis I and Meiosis II, at the end of the meiotic process, four daughter are produced, each of the daughter cells has one half of the number of the chromosomes as the parent cell.

IV. Mitosis v. MeiosisMeiosis is basically the reproduction of sex cells, after that process, the daughter cells have 1/2 the number of chromosomes as the parents cells. While Mitosis is the reproduction of the body cells, after going through it, the new daughter cells will have the same number of chromosomes as the parent cells. Also Diploid has 46 chromosomes and Haploid has 23 chromosomes. Haploid cells have half the number of chromosomes while Diploid has two times the chromosomes then the Haploid cells.
