  They are hypertonic to the water they are in. They need to use their contractile vacuoles to rid their body’s of excess water.

  Freshwater protists have remove water that rushes into their plasma membrane by simple diffusion all the time. They use their “contractile vacuole” to pump the water out otherwise they would lysis and burst. The contractile vacuole is a osmoregulater. A cell wall helps PLANT protists because the cells will not lysis/ burst because of the cell wall. I don’t believe that is a regulater though.
