Mitosis and meiosis are the two major processes by which eukaryotic cells reproduce. Compare and contrast the processes of mitosis and meiosis. Consider the stages involved in each and their eventual products. How are the differences biologically significant relative to growth and reproduction? Be prepared to discuss how life is dependent upon both types of cellular reproduction.
Mitosis is equal division of a cell and Meiosis is specialized type of cell division of chromosomes within a cell.
Mitosis goes through four stages in order: prophase; metaphase; anaphase; and telophase. The first phase, metaphase, is when the chromosomes become visible under a microscope and the cells stop all other processes. Then the chromosomes line up in the center of the cell to divide up equally during metaphase, a structure called the metaphase plate develops microtubes.
Once lined up, the chromosomes begin to pull apart at the beginning of anaphase. The opposite ends of the cells will begin to develope, or the polar regions and another set of microtubes start to develope here. At this point the chromosomes start to pull at the poles and the sets break up with one set going to one pole and the other going the opposite.
When the nuclear envelope starts to reform and the chromosomes begin to uncoil the Telophase has started. This is a 4stage process of separating the chromosomes or karyokinesis and the last being cytokinesis at the end of telophase. Results are copies of each chromosomes moved to each daughter cell. Meiosis’ specialized cell division happens during reproduction. Cellular division starts just like mitosis; the copied chromosomes come together in pairs, or homologous, in similar size, shape and length. The pairs separate here and go to different daughter cells, reducing the number of different kinds of chromosomes even if they are still connected. Then the copies are separated from each type of chromosome group going to a
