It was ridiculous seeing as i literally combed through two different books (one of which was approved by the aqa exam board) and a website and never saw any mention of magnesium ions being used by plants.

That question wasn't hard though apparently they told you it made chlorophyll so the rest is application of knowledge.

I saw that and WTFed, but it mentioned that a magnesium ion is needed for chlorophyll, so I answered along the lines of the magnesium being a requisite for chlorophyll which is needed for photosynthesis, which is responsible for glucose production, and that glucose is used for many things, such as starch stores/cellulose cell walls.


I'm clueless as to what the mark scheme will be like for some of the questions though, like the this question and the shrimp questions.


Does anyone have any idea whether this will be correct for the mating question?
I put something along the lines of 'Just because they did not mate does not mean it is impossible for them to interbreed to produce fertile offspring" and "aggressiveness doesn't particularly mean that interbreeding isn't possible".


Also, for the bladderwrack question, I put that they are adapted because they are found in a specific part of the habitat in one cluster, which would indicate that they have found a niche and that they are specifically adapted for these conditions, in contrast to the lettuce which is found in across a range of environments. Is this worthy of any credit?


Thank you, and best of luck on exams everyone

the Magnesium ion question should never have been put in! I am a teacher and this question or anything about Mg is not in the syllabus anymore!, with enough support from teachers we need to appeal and lower the grade boundary by a mark or 2!

I think the magnesium question wasn't too difficult because it told you they are found in chloroplast.. like others have said, you should be able to work out the photosynthesis link.
