Regulation of flower of solvent through osmosis process is known as osmoregulation such as in our kidney henles loop act as a semipermeable membrane and solvent like water hoes in and out through change in concentration of of salts it All happen with osmoregulation because of osmosis
Osmoregulation is the process by which the internal preassure of the organism is controlled. If we are talking about plants then they use osmossis to suck/move water through into the plant. Hence Osmo-regulation.
