I have done an investigation about the effect of acid rain on germination 
of cress seeds. I used solutions of sulphuric acid rangig from pH1-7. 
However, I cannot seem to find any scientific explanation for why the 
sulphuric acid affects germination. ANY information will be of help even 
if it is related to experiment itself.  Thankyou.
