The significance of meiosis :-. 1. It maintains the same chromosome n umber in the sexually reproducing organisms. From a diploid cell, haploid gametes are produced which in turn fuse to form a diploid cell. 2. It restricts the multiplication of chromosome number and maintains the stability of the species. 3. Maternal and paternal genes get exchanged during crossing over.
As a relatively short phase in the cell cycle, mitosis can be simply described as the multiplication of cells, without the need of undergoing sexual reproduction. Although the concept may seem to pose some complexity, mitosis is one important process among living beings. In the process of mitosis, the cell divides its contents, and eventually two cells emerge. Most single celled organisms such as plants, bacteria and fungi, undergo this type of reproduction. This one process is important because it enables the cells to reproduce and regenerate tissue in the body.
