The 'bladders' (air sacs) in the seaweed allow it to stand upright underwater as the air pulls it towards the surface of the sea as air is less dense than water. This allows it to absorb more light energy from the sun, which is essential for photosynthesis! :smile:
The onyl reason I knew that was because one of the 2014 Biology papers had a question about bladder wracks and I remembered the answer :P

was the question about part of liver cell controlling enzymes the nucleus or ribosomes? So confused
I did a ton of revision, dont think it was that bad apart from some vague common sense questions and confusing calculations.

Has anyone got the unofficial mark scheme ?

Same. That's why I knew I should write carbon dioxide/light and not oxygen.

I found the aqa higher tier exam really easy! I dont think I had a problem with a single question, and the 6 marker was a blessing.
Yep, flopped that really bad. could not have done any worse :frown:

Now, I'm seriously worried about the other cores :3
me too, the others who took the test said that it was easy...all that revision for nothing T_T
Hi, I said the air sacs provide carbon dioxide for the bladder wrack. carbon dioxide is needed for photosyntheses which provides energy for more growth.. is that right?

That's what I wrote
