Structurally and functionally, how do the daughter cells produced from meiosis differ from those produced my mitosis?

During mitotic cell division, two diploid daughter cells are produced from a diploid parent cell. They are exact replicas of the parent cell and can be used for growth in the body and replacement of damaged cells. In simple life forms, mitotic division allows for budding, binary fission, sporulation and regeneration of lost parts. All of these are examples of asexual reproduction. In mitotic division, there is a replication of the chromosomes of the parent cell. This step insures that the two daughter cells will each receive an identical complement of chromosomes. Meiosis is a reduction division, and occurs within a teste or ovary cell. After gametogenesis occurs, the outcome will be four haploid cells. If it is a male, spermatogenesis results in four haploid sperm cells. If it is a female, gametogenesis results in a haploid ova or egg cell. Meiosis allows sexually reproducing organisms to maintain the diploid chromosome number after fertilization takes place.
