SpletCell division. and growth. mitosis. In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. SpletA special form of cell division needed to produce sex cells - for example, sperm and eggs with only one copy of each chromosome. Fusion of the sex cells creates a new individual with two copies of each chromosome. Many single-celled organisms reproduce by cell division and have a single copy of each chromosome.
