(From Wikipedia, the free Encyclopedia)
Cell division is the process of a biological cell (called a mother cell) dividing into two daughter cells. This leads to growth in multicellular organisms (the growth of tissue) and to procreation (vegetative reproduction) in unicellular organisms.
Multicellular organisms replace worn-out cells through cell division. However, in some animals, cell division eventually halts, and the cell is then referred to as senescent. Senescent cells deteriorate and die, causing the body to age. Cells stop dividing because the telomeres, protective bits of DNA on the end of a chromosome, become shorter with each division and eventually can no longer protect the chromosome. Cancer cells, on the other hand, are "immortal." An enzyme called telomerase allows them to continue dividing indefinitely.
- Binary fission is the form of cell division used by prokaryotic cells.
- Mitosis is the most common form of eukaryotic cell division. A cell which has reached certain parameters or conditions (size, volume, stored energy, environmental factors, etc.) will replicate its entire nuclear DNA compliment and divide into two (usually equal) daughter cells. Both cells remain diploid or haploid, depending on the mother cell.
- Meiosis is the division of a diploid cell into (four) haploid ones. This cell division is found in multicellular organisms to produce haploid gametes, which can later fuse to form a diploid cell called a zygote.

 | Shown is an artist's rendition of normal cells and cancer cells undergoing cell division, showing the characteristics of both. See artwork: GR-23. Credit: Pat Kenny (artist). |  | Pictured is a scanning electron micrograph of cultured HeLa cells originally derived many years ago from a woman's cancerous cervical tissue. A light micrograph (x130) of the same cells (inset) reveals rounded double cells in the center in the process of dividing. This HeLa cell (named after patient Henrietta Lacks) has been infected with adenovirus. After 4-1/2 hours the HeLa cell's surface becomes rough. The multiple surface blebs on this cell characteristic for a certain stage of cell division that both normal and cancer cells go through. Research with the SEM has established the extraordinarily responsive nature of cell surface form. This instrument records, in pictures, specific cell reactions to various changes in the cells environment and maps the distribution of surface binding sites for biologically important molecules such as hormone, antigens, and pharmacologic agents.
