Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The genetic information of plants, animals and other eukaryotic organisms resides in. Growth in an organism is carefully controlled by regulating in order to examine cells in the tip of an onion root, a thin slice of the root is placed onto a microscope slide and stained so the chromosomes will be visible. An onion root tip is a rapidly growing part of an onion and thus many cells will be in different stages of mitosis.
