OCR Biology Evaluative - URGENT

I have a retake of an AS evaluative tomorrow, the only thing I have been told is that its on 'the effect of intracellular ion concentrations on model plant cells' I have no idea what to revise! Has anyone done this test and know what questions are going to come up? Please help :frown:(((((
How did it go? I have that one soon and would be great to know what to revise :smile:
