Which of the following is not correct with respect to mass flow hypothesis?

Water potential gradient between the absorbent and the liquid imbibed is essential for imbibition. In addition, for any substance to imbibe any liquid, one of the following is also a pre-requisite

Incipent plasmolysis is

Find out the correct pair of statements :
(i)  In completely plasmolysed cell, pressure potential does not contribute to water potential.
(ii)  If a cell is placed in hypotonic solution for longer time, the cell membrane shrinks away from its cell wall.
(iii) Apoplastic system comprises inter-connected protoplasts.
(iv) Polypeptides have more imbibing capacity than polysaccharides.

Water potential of pure water at standard temperature is equal to
