Investigation: Mitosis and Cancer Cells
The first part of this investigation, students examine slides of mitosis in an onion root tip and count the number of cells in each phase of the cell cycle. An equation is then used to estimate the percentage of time the cell spends in each phase and students create a bar graph to display results. …
