Daughter cell
In biology, daughter cells are the two cells that emerged from a parent cell after cell division .
The prerequisite for the development of daughter cells is the duplication of all organelles in the mother cell, including the genetic make-up . The division into two daughter cells, which only takes place after the cell body has been completely constricted, is therefore preceded in eukaryotic organisms by a nucleus division in the form of mitosis .
In some cases there is no division into two daughter cells, as is usual, but rather a multiple division of the original cell body into several daughter cells. In these cases, the number of cell nuclei in the starting cell must have multiplied before division so that each daughter cell receives a cell nucleus.
The etymology of the term daughter cell and the parent cell preceding it , especially with regard to the female gender (daughter cell as opposed to son cell, mother cell as opposed to father cell) are unclear. It is certain that these terms were already used in this way in the time of Rudolf Virchow. Obvious is the derivation from the Latin term cellula, which is feminine. In Italian, the term cellula figlia is still used today. However, the word "daughter" as a reference to "descendant" is also combined with masculine suffixes, for example with daughter clone.
