REQUIRED PRACTICAL 3 (OSMOSIS) - AQA A LEVEL BIOLOGY

In this video, I take you through the third required practical for AQA A Level Biology - Production of a dilution series of a solute to produce a calibration curve with which to identify the water potential of plant tissue.
I also go through an exam question related to the practical.
If you have any questions, please leave a comment - I'll be delighted to answer them!

Thank you so much
Thus will help for my mocks

[@kingdrivendust]

so helpful thank you so much. Would you ever do videos runnning through each paper like practise questions

[@AlevelBiologyHelp]

I have thought about that, but I am wary that a lot of teachers use past exam papers for mocks, so I don't want anyone cheating. I have also heard of some youtubers getting copyright claims for this in the past :(
