Scribepost period 8


Friday in class, Mr. Paek first said some announcements about the test and things coming up in class. Then, we went over the lab.




ANNOUNCEMENTS

  • Test Wednesday
  • Bio Day Tuesday
  • EXTRA CREDIT: cell theory objectives page 1= CROSS OUT #10-14
  • Study Session Tuesday after school for test Wednesday




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
