Question

What will be the effect on contractile vacuole, if Amoeba is place in marine water,

Answer 1

Answer:

Marine amoebae do not have contractile vacuoles because the solute concentration in seawater is higher outside of the membrane, so there is a net diffusion of water out of the organism.Salt water is hypertonic as compared to the solution inside the Amoeba cell. When Amoeba is placed in salt water, it will lose water by exosmosis and will shrink.
