Definitions:

Diploid Cells

Cells that contain two complete sets of chromosomes, one from each parent, typical of the somatic cells in animals.

Haploid Cells

Cells that contain a single set of chromosomes, half the number of chromosomes of a diploid cell, characteristic of gametes.

Centromeres

The region of a chromosome where the two sister chromatids are most tightly connected, playing a vital role in chromosome segregation during cell division.

Mitosis

A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
