Well according to my teacher, she said that plant growth is a subject which might come up - so I'm paying particular attention to that. Plus, what I am doing is going through the past papers and instead of writing essays, I am learning the answer scheme for pretty much all of the questions. The questions are pretty much the same but are changed slightly each year.

scholar's pretty good for the marking schemes.
Just remember to answer the question, and don't go off in a tangent!
Definitely wouldn't be happy doing a essay on meiosis or Protein synthesis!

The paper was very fair last year. 
There's a book with all the possible essays in - can't remember the name though.

Meiosis was in the essays last year so it shouldn't come up again this year, although you never know!
Protein synthesis isn't too bad surely?

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!

My bio teacher had looked at recent past essay questions and gave some suggestions to what could come up.
1. Aerobic respiration and comparing anaerobic and aerobic in animals (EDIT: Should say 'Aerobic respiration and compare anaerobic respiration in plants and animals)
2. Photosynthesis - photolyis, carbon fixation, structure of chloroplasts
3. Succession
4. Plants and how they are able to defend themselves
5. Water balance in kangaroo rat and fish
6. Protein synthesis
7. Homesasis - blood ugar, ADH etc
8. Role of IAA in plant growth, differntiantion of meristem tisue to xylem and phloem
9. The effects of chmical on growth - i.e minerals, vit D, calcium, etc
10. Finding food in animals - optimal foraging, territorial behaviour, cooperative hunting.
Please note that the above possibilities do not necessarily mean anything and the fact is, anything can come up in the course. However, the above is an 'educated guess' from my teacher who found some of the above topics not coming up recently. So, please, the above is just possibility

I think i would be snookered if i had to write on number on IAA or the the water balance!
I think we had to do our own notes on that.
What would you write on the the 1st question?

Oops. I apologise
I wrote it down wrong. That is maybe why it confusd you - it didn't really make sense I have edited the post.
For the first question:
a) chemistry of aerobic repiration - glycolysis, Krebs cycle, Cytochrome system
b) Differences in anaerobic resp. in plants and animals: plants -> ethanol and carbon dioxide produced. In animals -> lactic acid produced. You could also talk about anaerobic resp. in general. E.g only glycolysis takes place, therefore only gain of 2 ATP
Even I had to learn IAA and the whole hormone topic:
IAA is an auxin which are hormones whcih promote the growth of plants (i.e. cell division, elongation, differentiation)
High IAA:
Stimulates shoots (shoots -> up -> i.e stimulated growth)
Inhibits roots (roots -> down -> i.e inhibited growth)
Inhibits lateral buds
Stimulates fruit growth
Low IAA:
promotes leaf fall
(Note. Inhibits does not mean that the plants will become smaller, but that it will not grow as much as the control plant)
Cork screw, did you try to use the Torrance book to try and revise it? I generally find this book difficult to revise with and that is why it is a course book. The problem is, it's written in paragraphs which maker harder to take things in. The chemcord book is GREAT. It condenses everything without compromising course coverage.

Thanks!!
Yes, that big heavy plonker of a book - torrence!
Most of the info in that is completely unasked for!! I spent ages poring over every page - found to my dismay that the book goes over the requirements!!
Too late now...i'm going to have to have to go in cold turley.

The chemcord revision book is great for Biology.
You can buy it from amazon:
