Question

What is a contractile vacuole? State its function in Amoeba

Answer 1

Answer:

$\huge\red{Required Answer}$

Amoeba is a unicellular organism. A contractile vacuole works just the same as the name suggests, in that it expands and contracts. The function of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure.

Answer 2

Answer:

Amoeba is a unicellular organism. A contractile vacuole works just the same as the name suggests, in that it expands and contracts. The function of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. Contractile vacuole, regulatory organelle, usually spherical, found in freshwater protozoa and lower metazoans, such as sponges and hydras, that collects excess fluid from the protoplasm and periodically empties it into the surrounding medium. It may also excrete nitrogenous wastes.

Explanation:

The contractile vacuole acts as a protective mechanism that prevents the cell from absorbing too much water and thus preventing rupture of the cell (lysis) because of excessive internal pressure.
