Webmitosis. 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 … WebUnder normal circumstances, cell proliferation is regulated by a number of controllers (positive and negative controllers) that activate and stop cell division. Therefore, in such cases, cells can only divide a given number of times (e.g. replace cells lost during an injury) before they die off or enter growth arrest (the G0 phase).
