Yes they were both high in comparison to other parts of the cell. Magnesium is essential for chlorophyll which is only found in chloroplasts. and as it was day time plant was actively photosynthesizing so oxygen was also high in conc.

In paper 2 Q2 in which they asked that which pollination takes place... I wrote self pollination.. is there any chance that it can be correct??

 

[FayadC]

It's insect-pollinated. The plant's actual name is Indian Pipe. Check the internet.
I dunno what the mark scheme will accept.
But if it's insect-pollinated, can it be self-pollinated? If the answer to that question is yes, then they should accept your answer as well.
I really am not one to comment on this. I am just glad I got it right.

It was wind pollinated. The flower was not colourful, it was white. Therefore insects will not be attracted to the flower.

lol I may be wrong, but i have confirmed it from a number of sources and found that this particular flower is insect pollinated

 

[Bilal Mir]

You only had to take into account the information which was given. Sharp leaves, white colour are all characteristics of a wind pollinated flower.
