The diagram below shows how a paramecium maintains homeostasis. A parameciums normally lives in a hypotonic environment in which water continually diffuses into the cell. To maintain homeostasis, the
paramecium must pump out large amounts of water using its contractile vacuole.
Paramecium in a Hypotonic Environment
Pumping of water out
paramecum by vacuole
Higher salt
concentration
Lower sa
concentration
Diffusion of water into paramedum
If the paramecium is then placed in a hypertonic environment, which of the following will occur?
O Salt will be pumped into the paramecium by the vacuole
o Water will diffuse into the paramecium
O Salt will be pumped out of the paramecium by the vacuole
O Water will diffuse out of the paramecium
