many fresh -water one-celled organisms have structures called contractile vacuoles. these structures collect and pump out excess water that accumulates in the cell. what is the process that causes water to flow into these organisms and why contractile vacuoles would be of little value to one-celled organisms living the ocean (salt water)

The process that causes water to flow out is called osmosis. Contractile Vacuoles would be of little value b/c in the salty ocean water has the tendency to leave the cell- water goes from low salt solutions to high salt- the ocean being salty- So the cell wants to keep all the water in itself.
