PAG 5 – The effect of temperature on membrane permeability
Results table:
Temperature (degrees Celsius) Light absorbance (Au)
20 0.2454
30 0.2672
40 0.2900
50 0.5380
60 1.0500
Graph:
This graph shows that as the
temperature increases the
leakage of pigment from the
beetroot cells also increases
so there is a higher
absorption rate the higher
the temperature as there is
also more pigment.
