Ivo:
How do we work out the SA of the leaf?  What method?

And how do we answer this question:

"Describe how you obtained an answer that was as accurate as possible." (2 marks)

Many thanks guys!

What, so the one in red is the right one then?  And C is the micropyle?

Many thanks!

Count squares fully occupied by leaf as one cm...each one with 1/2 area occupied by leaf is counted as 1/2 cm...neglect those with less than 1/2
DONT COUNT SQUARES OCCUPIED BY PETIOLE

Thanks.  How about one's that are nearly occupied (e.g. box on 6th column, 2nd row)
