This was all seen in 400x total magnification. The cell cycle is composed of interphase (g₁, s, and g₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and g₀ phase. Interphase (not part of mitosis) is the everyday stage of a cell's life.

Cells regulate their cell cycle in two distinct ways:

Interphase, which appears to the eye to be a resting stage between cell divisions, is actually a period of diverse activities. For example, each human cell possesses 46 chromosomes, while each cell of an onion possesses 8 chromosomes. By using actively dividing cells in the onion root tip, this experiment aims to obtain a karyotype from the sample and to determine the purpose of each step used in the. During nuclear cell division they are found in special regions the onion root tip appears to spend most of its lifetime in interphase.
