There's a high concentration of sucrose in phloem than in leaf. So in order to move a substance against the conc. gradient, active transport is required. As more and more sucrose will move into the phloem, this will lower the water potential. So it will get more negative.

You mean topic wise? Or like all years and sessions together?
Yes, Topic Wise by Chapter.
Formed with Complete Sentences, not like the confusing Marking Scheme, that wants us to fill in the blanks...

About AS I made some notes myself but they are less,not for every chapter even.
