Osmotic water permeability (Pos) was measured in protoplasts isolated from different tissues of Phaseolus vulgaris twining shoot. Parenchyma protoplasts exhibited more frequently high Pos values than epidermis protoplasts did. Water channels could facilitate water movement between parenchyma cells whereas cell-to-cell water transport mostly occurs through plasmodesmata in epidermis.
