WebMitosis is a cell division mechanism that produces genetically identical new cells. Mitosis aids in the growth of organisms and the repair of damaged tissue. Growing and generating children is possible for all living species. Mitosis is a process that all eukaryotic organisms go through to grow, including aquatic plants and algae. WebIn multicellular organisms, tissue growth rarely occurs solely through cell growth without cell division, but most often occurs through cell proliferation. This is because a single cell with only one copy of the genome in the cell nucleus can perform biosynthesis and thus undergo cell growth at only half the rate of two cells.

In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.
