Explain your results. Why did some of the The paramecium (sec Figure 3-1) is a single-celled organism. Go to the web and look up this organism. Now select an answer from each blank. Paramecia live in a (n) (iso-, hypo-, or 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 to expel water through the process of (osmosis, diffusion, facilitated diffusion, or active transport).
Explanation / Answer
Paramecia lives in hypotonic environment.
The contractile vacoule that act as a water pump to expect water by the process of osmosis.
