How does paramecium maintain water balance?

Contractile vacuoles maintain water balance by expanding and contracting. The main job of contractile vacuoles is maintaining water balance, which is… See full answer below. Our experts can answer your tough homework and study questions. Contractile vacuoles are membrane-bound organelles that exist mainly in the cells of the kingdom Protista.

How does Paramecium regulate the movement of water?

What process allows the vacuole to fill with water?

If there is too much water, the contractile vacuole works to pump out the water. This helps to protect the cell: if there is too much water in the cell, it will swell and swell until eventually it ruptures, destroying the cell. Contractile vacuoles keep this in check.

Contractile vacuoles maintain water balance by expanding and contracting.

The contractile vacuole is an organelle found in paramecia, a group of single-celled organisms. Contractile vacuoles pump out fresh water that accumulates in the organisms by osmosis. Explain how this is an example of the way paramecia maintain homeostasis.

A paramecium maintains homeostasis by responding to variations in the concentration of salt in the water in which it lives. (The concentration of a solution is equal to the amount of solute that is dissolved in a given amount of solvent.) Question: How do changing solute concentrations affect a paramecium?

The contractile vacuole (CV) complex is an osmoregulatory organelle of free-living amoebae and protozoa, which controls the intracellular water balance by accumulating and expelling excess water out of the cell, allowing cells to survive under hypotonic stress as in pond water.

Experiment: The contractile vacuole is a star-shaped structure that helps the paramecium to pump out excess water. This adaptation allows the paramecium to survive in hypotonic (low solute concentration) solutions.

Contractile vacuoles are responsible for osmoregulation, or the discharge of excess water from the cell, according to the authors of “Advanced Biology, 1st Ed.” (Nelson, 2000). Depending on the species, water is fed into the contractile vacuoles via canals, or by smaller water-carrying vacuoles.

Osmoregulation. Paramecium and amoeba live in fresh water. Their cytoplasm contains a greater concentration of solutes than their surroundings and so they absorb water by osmosis. The excess water is collected into a contractile vacuole which swells and finally expels water through an opening in the cell membrane.
