WebMar 29, 2011 · Mitosis is the type of cell division that occurs in the vegetative cells of the organism while meiosis occurs in the reproductive cells of the organism. Some of the specific processes and products of meiosis differ from that of mitosis. Mitosis involves division of parent cells into two identical daughter cells that are same as that of parent cell. Websignificance of crossing over in meiosis - Example. Meiosis is a type of cell division that occurs in sexually reproducing organisms, including animals and plants. One of the key features of meiosis is the process of crossing over, which plays a crucial role in the production of genetically diverse offspring.
