Answer to Question #100003 in Zoology for amna

Question

how protozoa maintain osmoregulation?

Answer 1

They have contractile vacuole in it.  The contractile vacuoles make it possible for a protozoan to get the water out. The vacuole becomes progressively enlarged by collecting more and more water and releases the contractile vacuole through trailing end of the body through pseudopodia in Amoeba.
