Which of the following is true/false regarding transport of substances in plants ? (i) Mass flow is the movement of substances in bulk as a result of pressure difference (ii) Bulk flow is achieved only through a positive hydrostatic pressure gradient (iii) The apoplast system is the system of interconnected protoplasts (iv) Most of the water flow in the roots occurs via the apoplast since the cortical cells are loosely packed, and offer no resistance to water movement.
