    I think i already said that if final twmp. is 90 how is it not possible, 90*C does not exceed boiling point of water , read the whole question not just the marking scheme GENIUS:p

    i know why :cool: , beause on the upper surface of the leaf the pallisade mesophyl is present which is dense hence less vapour escapes from the upper surface thus lesser waxy layer but on the under side there is spongy mesophyl whichis loosey packed and has many air pockets, more water loss thus...
