Mitosis VS. Meiosis

All living things are made of cells from bacteria to the most complex being on earth us. These cells must reproduce in some way one method is mitosis that would take place in bacteria while, another way is meiosis one that you may have heard of in sex education. These, two processes may seem similar at first but as you take a closer look like we do in this essay you will learn that these processes are very different in many distinctive way ranging from how they take place to what is produced.

Mitosis is a type of cell reproduction in which the cell use less energy to reproduce faster but with less differentiation. Meiosis unlike mitosis is a complex form of cell reproduction in which a cell goes through many phases and crosses over creating great differentiation. Mitosis has 5 phases prophase, metaphase, anaphase, telophase and cytokinesis. Meiosis has 2 main phases Meiosis 1 and Meiosis 2 and each has 5 sub-phases prophase, metaphase, anaphase, telophase and cytokinesis. Mitosis’s prophase is the longest phase it is also the longest phase in meiosis 1 and 2 but in mitosis crossing over doesn’t occur so the alleles stay in the same order in mitosis but in meiosis 1 the alleles mix in crossing over and causes differentiation this does not take place in meiosis 2 though. Also, the centriole splits into 2 centrioles and begins forming spindle fibers this happens in both mitosis and meiosis. Metaphase the second phase of both mitosis and meiosis is also the shortest during this phase in mitosis spindle fibers are formed and attached to the centromeres of the chromosomes and line the chromosomes up across the center of the cell with two poles of the spindle connected to the chromosomes. Unlike, mitosis in meiosis 1 only 1 pole of the spindle fiber connects to the chromosomes. Anaphase in mitosis consists of the separation of chromosomes and pulling them to opposite ends of the cell but in meiosis 1 the...
