I. The apoplastic movement of water occurs exclusively through the cell wall without crossing any membranes.
II. Solutes present in a cell (or in any solution) increase the free energy of water or water potential.
III. The symplastic movement occurs from cell to cell through the plasmodesmata. IV.Membrane permeability depends on the membrane composition, as well the chemical nature of the solute.
