I forgot the word upper, I just wrote epidermis! Hope that doesn't cost me the mark!! Overall went pretty well I think. Biology is my favourite science.

I put it wouldn't have any guard cells or stomata, there would just be regular plant cells with the nuclei... There were 20 stomata right?

i think january papers tend to be harder than june papers because they are normally re-sits, so i dont think it will be as hard as jan 2015 but i am still dreading the exam tomorrow!

Exactly what I said to Mr. Bates but he said "no Zahra I don't think so!" Ugh

Some people at my school wrote something about osmosis and putting the potato in a sugary solution so that all the water comes out of potato but I thought that was wrong
