Investigation 2 – PostLab









Note: Questions marked with a triangle (∆) are included to enrich your understanding. These questions do not appear in your SDR but should be used as additional discussion points during the PostLab.

As a class, discuss the process of cell cycle regulation as the reason why different cells divide at different rates.

  • ∆ What phase of the cell cycle was the model of the inactive breast cell most of the time? 
  • ∆ Why do the embryonic and inactive breast tissue cells divide at different rates?

Complete the Apply question in your SDR then discuss it as a class. 


Complete the Focus Questions in your SDR then discuss them as a class. 

  • How do tissues replenish the cells contained within them? 
  • What controls the process of cell division?
