WJEC BY1 and BY2 Summer 2012

Were the xylem vessels the large ones right in the centre of the endodermis?

Yep

Thanks! I really hope they allow it!
do u think they'd allow endothelium instead of epithelium??

Anyone here do HB2?

i could've kissed the last qs on transpiration!

Did anyone do the reproduction 10 mark? I just talked about sexual and asexual. didnt know whether to talk about external or internal fertilisation so I didn't. What did everyone put?

I just talked about how wind movement, temperature, light intensity and humidity effect concentration gradient. And for second part just did the whole bubble potometer experiment from Jan 2012 past paper.

What about you??

For the symptom question about the valves I put Heart Murmur (only because I have one and remembered that is it to do with valves lol) but not sure if it will be specific enough.

Stupid question but for the Xylem and Phloem questions what did people put as the function? I think I was far to vague (there was so much writing space and I wrote like 5 words :/ )

My drawing of the endodermis cell with casparian strip was shocking and I messed up the explanation by writing the wrong route!! Stupid marks lost - really frustrating.

Agree with everyone about them using the smaller topics rather than the main topics you would assume that would come up - WJEC at it's best!

I might have blagged a few marks including the one that asks about the cell in the digestion question (goblet cell apparently) I didn't have any idea of it's name but remembered something produced mucus lol

Like others with the Autotrophic ect questions I was vague although I will say that in the past papers relating to Parasite questions, they specifically wanted the name for a tapeworm (Taenia Solium) luckily I remembered the name and wrote that but wrote tapeworm after too. The others I wrote plant and fungi (WJEC might be nice and allow them - or not)

Overall a pretty crappy exam. Not really sure how I did because WJEC are insanely unpredictable. Now for my A2 exams in a few weeks... eeeeeeeeeeeeeek! Good luck to everyone with exams still to go.

I totally totally agree with you!!!! WJEC is just so vague, one year they may allow one thing and the next they might not! My one friend believes that if you sit a paper again with like no more extra revision you'd get more as it all relies on the mark scheme and whether they're in a picky mood or not.

I have my A2's soon too, BY5 is looking slighty nicer although theres only like 2 past papers?!

Good luck!!

I didn't actually read the question properly until like the last 10 minutes. I wrote all about internal and external fertilisation at first then in the last 10 mintues wrote about sexual and asexual reproduction, hopefully that was enough
