Read the following statement and choose the correct one from the codes given below
I. The apoplastic movement of water takes place exclusively through intercellular spaces and cell wall without crossing any membrane
II. Symplastic movement occurs from cell to cell through plasmodesmata, ., adjacent cells are connected through plasmodesmata
III. Permeability of a membrane depends on its composition and chemical nature of the solute
IV. Solutes present in a cell increases the free energy of the water or water potential
