OCR AS Biology F211 - Unofficial Mark Scheme

Sounds pretty Greek to me, but I think that should get you credit

I don't know, it's one of those where they'll either do ACCEPT or IGNORE with vein. Vascular bundle's the safe bet. Vein by itself I don't think would get the mark, but vascular vein might

Do I get a mark for putting flagellum instead of centrioles in Q1?
Do I get a mark for putting 16.6 hours because that is more accurate than 17 hours?
Do I get a mark for putting organelles instead of ultrastructure in the last question?

for the definition questions i just put homologous instead of homologous pair, will i still get the mark?

i put " Vein (Vascular Bundle) "

do you think they'll ignore/only mark the first given answer?

for the definition questions i just put homologous instead of homologous pair, will i still get the mark?

Also, for how the microorganism question i said they can communicate by moving to find better environmental conditions as that was in the text is that still right? and for the gap fill i said diffusion gradient and not concentration gradient and in all the OCR books it says diffusion so will i get this mark too?

It took 16.6 hours to get from two cells to 100,000 cells, so add an hour on to account for the first cell division and you get 17.6 hours, right? Also, I wrote pressure gradient for why the balloons inflate question and then edited it to "pressure potential gradient", would I lose marks because of this?

I put Proton gradient instead of concentration gradient, think that's alright? Electrochemical probably the best word but didn't think of it in the exam!

Someone answer this dude!

Is 16.6 hours (y) or (n)? :s

It is very likely that they will let you have 16.6 or 17 hours.

Thank you dude #2

Q) Also, cilia would not get the mark for a structure present in animal cells that is not in plant cells would it? :L

And could ya please put something up for the filling in the blanks thing? :s O:-)

Edit: I have arrived back from specsavers and have noticed you already put that up, thank youuuuuuu

I doubt they'll let you have that, but you can never be sure with the OCR mark schemes.

I think you've missed the one that asked what would a scientist see if he looked at the sieve tube element and companion cell through an electron microscope
