    it tells you in the question that the maximum age is something like 95.... so you find the percentage of the age at the specific amount... i think its 85% right??? but then you take 85% of 95 or whatever the maximum age is and it gets you the answer.

    What do we think the long answers are going to be at the end? Eutrophication and what else?

    Respiration, maybe?
    I've seen both parts of photosynthesis on the long answers in past papers but not any respiration yet (I think)

    Have you got the mark scheme for the photosynthesis one? That might come up?

    This is how i did it:

    The max rate will be steepest point on graph so get any 2 points on the steepest bit and just read off the graph


    25-20= 5

    400-200=200

    200/5 = 40.. do u get it? Hope it helps..

    intergranal lamelae increases SA for light dependant reaction, Thylakoids are stacked up in granum for maximum rate of light dependant photosynthesis.

    I get it now..but we meant to draw a line that crosses x-axis and then read off the graph

    (thats what we do in physics and chemistry)

    1. Contains both Dna and ribosome so it can manufacture protein needed quickly and easily

    2. Protein structure hold chloroplast in a precise manner that allow max aborption of light
