OFFICIAL OCR A2 Biology - F214 Thread

alsooo can someone PLEASE explain to me this:
in the photosynthesis module, there's a double spread about limiting factors, and basically all i can figure out is that carbon dioxide, light and water levels all increase photosynthesis rate? what else do we need to know form that double spread? seriously like, i have no clue what else that spread talks about? so confusing? what do we need to knowww !!

This post is nothing useful but just letting you know you're not alone. Photosynthesis - all of it - is by far my worst area. It's just not sinking in

thank goodness i've finally found a thread for this exam !!
arghhhh i can't believe how much there is to learn for just 30% aparrently? especially considering how many important processes there are which go into so much detail i.e. respiration and photosynthesis!
crazy times.
i'm probably having the most difficulty with understanding the hairpin countercurrent multiplier bit, like with the movement of salts across and all that crap, so confusing!!
also understanding non-cyclic photophosphorylation, it's so badly explained. i thought the electrnos moving along the electron carriers was to pump hydrogen ions into the thylakoid space but in the book all it bangs on about is how the energy is needed to make ATP and to reduce NADP...weird.
whoever posted those past paper questions is a god!!!
i have to do well in this exam, as overall for AS i got 239/300 which is one off an A, HOW FRUSTRATING IS THAT!???

haha good luck everyone

ahhhhh it is slightly comforting knowing that other people are slightly confused by the content of this STOOOOOOOOOOPID exam !!
rahh so annoyed, and i need to do well in this! grrrrrrr
btw has anyone applied to durham? i haven't got an offer yet and sent my ucas off in about october. fml

ok if it is soo, here is it guys you first need to download it from mediafire becoz the file is about 2.20mb exceeds thestudentroom limit

don't forget to rep+

Photosynethsis: http://www.mediafire.com/?1tnymydn5vt

Respiration: http://www.mediafire.com/?lngjzywlzzt

Homeostasis: http://www.mediafire.com/?53nwmnmwiwz

Excretion: http://www.mediafire.com/?mtngntoywtr

You do need Microsoft office 2007 to view it properly, otherwise you will have to sort out the questions if its out of place in the older Ms versions.
i believe this should be no problems for IT geeks lol

don't forget to tell me what you think of my post ok:P

I have compiled a file which is linked below, with all the questions relevant to the new specification from the Old Specification of 2804 (Central Concepts), so to save time searching for them and printing. Ive done this for paper's from Jan 02 - Jan 06.

(Sorry couldn't do them for June 06 onwards as the PDF files I have are protected so I can't edit them).

Thank you so much for this, it has really saved me a lot of time.

Would you, by any chance, be able to upload the mark schemes for these questions as well?

Like the rest of the papers, the Mark Schemes I have for the appropriate papers are all protected so My PDF Editor won't let me edit them. Ill look around If I can find a new bunch of them, If possible I'll upload them.

Ok guys heres the first installment with the question cards, they helped alot of ppl last year so hopefully theyll do the same this time . Umm if theres anything u think i have left out please tell me

the rest are coming soon, working on the hormone and excretion ones atm

So whats the hardest topic in this module any views ?

Hey guys, Hows it going?

I'm about to start revision...

I have done Photosynthesis/Respiration, but need to go over it to know the technicalities and match it up with the Spec.

I plan on doing excretion tonight/today ready for the Homeostasis module which looks terrifying!

Any updates on the question cards chuck ?
