Question

The main function of contractile vacuole in Amoeba is

• A. Respiration
• B. Osmoregulation
• C. Cell division
• D. Automixis

Answer 1

The correct option is B Osmoregulation

Osmoregulation is the process which takes place in unicellular protist. It regulates the osmotic pressure inside the cell. Vacuoles are the organs in Amoeba which are known for osmoregulation. It maintains the level of salt and water inside a cell. If the concentration of the salt is more inside the body the water is absorbed while if the extra water is released if salt concentration is less than the surrounding environment.

Thus, the correct answer is option B.
