What is the name given to the original cell before it divides?

The original cell that divides is called the parent (mother) cell, while the two, new identical cells are called daughter cells. A cell normally divides into two new cells (once it has copied all its DNA). This process is called mitosis. Each new cell gets a complete copy of all the DNA, bundled up as 46 chromosomes.

The cell cycle (stages in a cell's life) is made up of stages in which the cell grows and rests, copies its DNA, and divides into two new cells.
