H2O (iso-, hypo-, or nucleus oral groove Paramecia live in a(n) hypertonic) environment. In this environment, the paramecium takes in a lot of water through the process of (osmosis, diffusion, facilitated diffusion, or active transport). In order to get rid of this excess water, the paramecium has a specialized organelle called the contractile vacuole that acts as a water pump -contractile vacuole to expel water through the process of (osmosis, diffusion, facilitated diffusion, or active transport).
