Definitions:

Mitosis

A kind of cell division that produces new cells having exactly the same number of chromosome pairs, and hence copies of genes, as the parent cell.

Cell Division

The process by which a parent cell divides into two or more daughter cells, critical for growth, reproduction, and repair in organisms.

Parent Cells

Cells that divide to produce daughter cells through the process of mitosis or meiosis, involved in growth, repair, and reproduction in living organisms.

Sister Chromatids
