1. Why do we use beetroot cells to measure the effect of different variables on membrane permeability? 2. If a lot of pigment leaks out, what does this tell us about the membrane permeability? 3. If only a little amount of pigment leaks out, what does this tell us about membrane permeability? - ANSWER1. Because beetroot cells contain a coloured pigment (dark red/ purple), that leaks out. 2. High membrane permeability 3. Low membrane permeability State the independent variable, d...
