What about 'define senescence'?? That had us all squeaking up here
(those sitting in Edinburgh). I've looked it up and I'm still no
wiser. From comments it seems that no course can hope to cover all the
random stuff the RHS has to choose from.




It was in a past exam paper, but when revising I couldn't find anything
about it. I waffled in the end about leaves changing colour and absyssic
acid.
