Explain why contractile vacuoles would be of little value to one-celled organisms living in the ocean (salt water)

In salt water, the solute concentration outside the cell is more than inside the cell so the water flows out of the cell down the concentration gradient. Therefore, contractile vacuoles are not required for expelling water.

The organisms living in an aquatic environment have to undergo osmoregulation and survive in a hypotonic environment. The organisms such as paramecium, protists, and unicellular algae have contractile vacuoles.

The functions of the contractile vacuoles include:

1. Contractile vacuoles help in the osmoregulation, such that the movement of solute particles inside and outside of the cells.

2. The contractile vacuoles are also required to remove excess water from the organisms.

3. The vacuoles contract to discharge the fluid for the survival of organisms like paramecium and algae.

Thus, the contractile vacuoles contract to allow the organisms to survive in a hypotonic environment.
