Investigating the effect of temperature on cell membrane permeability

Aim

The aim in this lab is to investigate the effect of different temperatures on

beetroot cell membranes

Hypothesis

I predict that the higher the temperature the more damage which will be caused

on the membrane. I think this will happen due to the temperature of the water

rising above the membranes temperature tolerance, causing damage.
