but more air spaces means more transpiration, no?

In a way yes

 

[***amd***]

When it is released after pulling, it will be in it's original position. That is the one shown in 1.1a

we have to draw its 'highest position, shouldnt that be the same distance above the normal line as it is down by the pull? coz this is oscillatory motion.

 

[***amd***]

In a way yes

then why cant i write it there in the answer? its not mentioned in ms. or, does that mean i am more genius than examiners?

Q1 (c) (ii)
why cant we give reference to "more transpiration in in leaves in light because of more air spaces to cop with the more heat of sun" here?

yes, i know .-.

gud then

 

[***amd***]

gud then

pardon?

Need some pointers and guideline on how to prepare for Bio ATP, botany and diagrams aren't my strong points

b) Describe the ways in which a plant obtains its oxygen for respiration.
need a good answer fr ds?? nyone?

From the air...and if they want the process, it's the reverse of photosynthesis!

You're right. The examiner report says "...Many candidates did realise that the mass would rise as far above
its original position as it was pulled down below its original position"

so tht means tht the ms was wrong......right?

ms is also right, read it again.
"point marked level with top of hook "
the level of the hook in fig 1.1 b
