A) contractile vacuole
B) pseudopodia
C) ectoplasm
D) cytostome
Correct Answer: A
Solution :
Contractile vacuoles are required for osmoregulation ie, maintenance of water balance within the body. These are found in the cytoplasm of those organisms, which live in hypotonic water. Amoeba is a good example of such type of organism. Entamoeba, an endoparasite, lives in the large intestine where the surrounding is hypertonic, so this organism does not have need of contractile vacuoles.You need to login to perform this action.
