Question

list one function of contractile vacule​

Answer 1

Answer:

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.

Explanation:

The function of contractile vacuole is osmoregulatory. Water in freshwater protozoa enters the organism by endosmosis and during feeding. If the organism does not possess a mechanism to get rid of this excess water, it will swell to the point of rupture and dissolution.

Answer 2

Lower species have contractile vacuoles, which are structures found in their cells. In excretion and osmoregulation, the vacuole performs a crucial role. Ammonia and other wastes can be expelled through the vacuoles. In order to maintain the osmotic balance, water and other salts are also eliminated through these vacuoles.

Many marine species have a structure called a contractile vacuole. It serves as an organelle, removing any extra water that may have accumulated in the cell due to osmotic circumstances.
