cell division
cell divisionn. The process by which a cell divides into two or more cells. Fission, mitosis, and meiosis are forms of cell division.cell division n (Biology) cytology the division of a cell into two new cells during growth or reproduction. See amitosis, meiosis, mitosis cell′ divi`sion n. the division of a cell or cells in reproduction or growth. [1880–85] cell division The process by which a cell divides into two or more cells. Cell division is the means of reproduction in organisms that reproduce asexually, as by fission or spore formation. In organisms that reproduce sexually, cell division is the source of all tissue growth and repair. The two main types of cell division are mitosis and meiosis.ThesaurusNoun | 1. | cell division - the process in reproduction and growth by which a cell divides to form daughter cellscellular divisionamitosis - the direct method of cell division characterized by simple division of the nucleus without formation of chromosomessegmentation, cleavage - (embryology) the repeated division of a fertilised ovummeiosis, miosis, reduction division - (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)mitosis - cell division in which the nucleus divides into nuclei containing the same number of chromosomesbiological process, organic process - a process occurring in living organisms | Translationscell division
cell division: see cellcell, in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. There are many unicellular organisms, e.g. .....

Meiosis occurs only in the process of gametogenesis, i.e., when the gametes, or sex cells (ovum and sperm), are being formed. .....

division [dĭ-vizh´un] the act of separating into parts.cell division fission of a cell, the process by which cells reproduce.cell divisionn. The process by which a cell divides to form two daughter cells. Upon completion of the process, each daughter cell contains the same genetic material as the original cell and roughly half of its cytoplasm.cell division the division of a cell into two new cells during growth or reproduction. The new cells are called daughter cells. In PROKARYOTES, two identical cells are produced by BINARY FISSION. In EUKARYOTES, cell division is more complicated because the genetic material is located on CHROMOSOMES inside the nucleus, being composed of two distinct processes that usually occur together; (a) nuclear division (MITOSIS producing two identical nuclei, or MEIOSIS producing four nuclei with a halving of the genetic complement) and (b) cytoplasmic division (CYTOKINESIS).LegalSeeCellFinancialSeecellcell division
