LAB
The lab is found on pages 48-51. The main idea of this lab, Time For Mitosis, is to figure out the differences between stages of a cell in mitosis. In this lab, we looked at different sections of a slide with onion root tip cells on it and identified the different stages they cells were in. We then put our information in a table and calculated the times for completion of the phases by using the formula:
time for phase = number of cells in a phase/ total number of cells counted x 720 minutes
For homework, finish pages 49-51
