Trapping Their Prey
Common trapping techniques are pitfall traps, flypaper traps, snapping traps, and suction traps. The first two use adaptations that involve shape and sticky surfaces. The last two are particularly fascinating, because the presence of prey triggers the plant to take action — to move, quickly!
Paramecium needs contractile vacuole due to its different environment from other protozoan that lives in salt water.
<h3>
Need of contractile vacuole for paramecium</h3>
In salt water, the solute concentration outside the cell is more than inside the cell so the water flows out of the cell down the concentration gradient. Therefore contractile vacuoles are not required for expelling water for most protozoan living in salt water.
While on the other hand, paramecium lives in fresh water so contractile vacuole is required for removing excess water so we can conclude that paramecium needs contractile vacuole due to its different environment from other protozoan that lives in salt water.
