Plan:- Independent Variable- Temperature is what I will be ever-changing in the experiment. I want to find out what nucleus temperature has on the permeability of a cell membrane. Controlling opposite Variables- I will practice measures to ensure that everything stays the akin in my seek to come along the best and about reliable results possible -         Same volume of weewee that I put the beetroot into after heating. -         The beetroot I function will be the selfsame(prenominal) size separately clock, I will ensure this         using a bottle bobtail stone drill. -         The beetroot will be heated for the same time for each one, also it         will be left         in the irrigate for the same time after. Equipment:- Beaker Thermometer Heat verification mat Tripod Bunsen Burner Cork Borer 10 beetroot cylinders Forceps 10 test tubes Colorimeter Measuring cylinder likewis e to improve the reliability of the test I will go the results. Method -         Heat 200ml of irrigate in a beaker -         Whilst piddle is heating, perpetrate 10cm3 of water into each of ten test         tubes. chase after 85-45 and tail in a water tubful at 20 degree         Celsius -         Cut beetroot with a bobtail borer to length of 5cm.
Use a borer with a         diam of 1cm -         Place the beetroot cylinder into a beaker of water at 85 degrees,         after one minute mathematical function forceps to rapture to test tube o! f water in         water         bath at 20 degrees celsius -         As water in beaker cools reprise step 3 using fresh cylinder of         beetroot. -         masterful this cycle for 10 cylinders -         Leave each cylinder in its test tube for 30 proceedings -         afterward 30 minutes remove beetroot and shake outcome well to defecate the         best quality colour -         dumbfound the solutions and transfer to small beakers and drift into the         colorimeters, change the setting...
