This guide is designed to provide you with an overview of the important processes involved in the reproduction of cells. Cellular reproduction is a process by which cells duplicate their contents and then divide into two cells with similar, if not duplicate, contents. Understanding this process is helpful in understanding the basis for human reproduction as well as the basis for the generation of life in other classes of organisms. Cell reproduction does not always result in new independent cells. It is also essential to growth and development as well as in the day-to-day maintenance of many human cells. This SparkNote will provide a general introduction to cell division and cell reproduction.
