Osmoregulation in unicellular organisms is by active transport.
For example in Paramecium - osmoregulation is done by organelles called contractile vacuoles. These contractile vacuoles are spherical shaped structures surrounded by a series of radiating ducts.
These ducts collect water and pump it into the central area by means of contractile fibres that contract and force the water into the center. When the vacuoles are full the unicellular organism contracts forcing the water outside the cell.
