What is cell division

Cell division

Synonyms: cytokinesis, cytokinesis
English: cell division

1 definition

The Cell division is a biological core process that ensures the growth and reproduction of all living things. It divides the cell plasma and other cell components of the mother cell into two or more daughter cells by creating separate compartments by drawing in new cell membranes.

2 background

In eukaryotes, cell division is usually preceded by a nucleus division, which distributes the DNA of the mother cell and thus the genetic information to the daughter cells that are created. A distinction is made between two forms of nuclear divisions, mitosis and meiosis.

  • In the case of mitosis, two daughter cells are created whose DNA is identical to that of the parent cell.
  • The second form of nuclear division, meiosis, leads to the formation of germ cells (gametes), which are used for sexual reproduction. During meiosis there is a reduction in the number of chromosomes, i.e. the cells are no longer diploid like their precursor cells, but haploid after they have divided.

Under normal circumstances, cell division is a strictly regulated process, the regulation of which is controlled by the cell itself, but also by the neighboring cells that surround it and hormonally by the entire organism. When cells divide in an uncontrolled manner in an organism, tumors develop. Malignant tumors (cancer) are the most serious of these disorders.
