Multiply the percentage of time in each phase by the total time of the cell cycle (720 minutes) and this gives you an estimate of the time spent in each phase.Įstimate of time spent in each phase of the cell cycle.

Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) and dividing each by the total number of cells you counted.

In an onion root tip, the entire cell cycle takes about 12 hours or 720 minutes.

Identify the phases of the cell cycle for 25 randomly chosen cells.

This area of the root is undergoing rapid cell reproduction. Work as a team to look at onion root tips under the microscope.This exercise uses onion root tips to illustrate the amount of time spent in each phase of mitosis. In plants, an area of rapid growth is the tips of roots. The whole process of mitosis, prophase to telophase, takes approximately 90 min. Some specialized cells like nerve and muscle cells almost never reproduce and are in a special stage called G 0. Skin cells reproduce frequently (about once per day) liver cells reproduce rarely (about once per year).
