    A. B is transpiration pull.
    Who negged this? What I said is correct, straight out of the NT book!

    That's much better, by the way sorry what book do you have if you don't mind me asking because I want to start learning A2 early?



    No wonder, that's the paper I done as a mock. Let's just hope AQA don't pull any new tricks out the bag!
    My book is AS only, but they have an A2 book in the same series as well. Its AS Biology for AQA by Michael Kent. I thinks its got a pretty good definition list in the back, and its easy to read as they cover pretty much everything you need in ever double page spread, and they give enough good images to help you understand.
    http://www.amazon.co.uk/s/ref=nb_sb_...5267-4&x=0&y=0

    And the A2 level link:
    http://www.amazon.co.uk/s/ref=nb_sb_...5267-4&x=0&y=0

    My school also gives the book by Bill Indge, but i thinks its pretty awful to be honest. Here's the link anyway:
    http://www.amazon.co.uk/AQA-Biology-...ref=pd_sim_b_5

    Hope this helps

    Sorry that was me-my textbook defines transpiration as "the upward moving column of water from the root cells to the stomata", which is pretty much the answer that will get you all the marks in a definition, based on mark schemes. A is just evaporation, it speeds up transpiration rate by creating a water potential gradient.

    What is the definition of a taxonomy?
    the theory and practice of biological classification
    source: Nelson thornes text book
    i highly doubt they will ask for the definition

    Well my textbook (the official one that's endorsed by AQA) says that transpiration is the evaporation of water vapour from plants. So does wikipedia for that matter. What you're describing is called Transpiration Pull.

    You could have asked me this instead of negging me :P

    My book defines transpiration as loss of water from plants surface :/

    Thanks Jim Definitely helped i think you accidently put the AS link for A2 too but got it thanks:http://www.amazon.co.uk/A2-Biology-A...ref=pd_sim_b_3

    Thanks for it anyway, if it's awful definitely not using it I get confused easily enough anyway! +ve rep but me being new i've finished for today, so tommorow

    Good luck for the exam

    Grade boundaries are really low for this paper xD its about 62-67% for an A

    For the jan 11 paper you needed 64 raw marks for 140 UMS.
    How can you be so sure? Don't they decide after they mark?

    Technically yes-but they usually find that a lot of people only get around 65-70%. Apparently exam boards use the standard 80%=A, 70%=B usually, but because they write harder biology exams, they lower the grade boundaries. You also only need about 87% for them to scale up your mark to full UMS marks-i think its probably because very few people or no-one gets full actual marks, so they have to make it a bit fairer.
