Plant cells will gain or lose water to intercellular fluids depending upon their water potential. Contains integral transport proteins that control the movement of solutes between the cytosol and the vacuole. Has a membrane potential. Several solutes are transported between the cytosol and vacuole due to this membrane potential and proton gradient. Across the plasma membranes and cell walls.
Solutes move from one cell to the next by repeatedly crossing plasma membranes and cell walls.
The symplast route. A symplast is the continuum of cytoplasm within a plant tissue formed by the plasmodesmata which pass through pores in the cell walls. Once water or a solute enters a cell by crossing a plasma membrane, the molecules can enter other cells by traveling through the plasmodesmata. The apoplast route.
