The whole plant. Common Bladderworts float in the water, with an extensive network of roots in the water.
Here the bladders are visible, scattered amongst the roots. These are how Common Bladderwort obtains its nutrients. The bladders are filled with air. When a tiny animal bventures too close it triggers a trapdoor which springs open and sucks the animal inside, where it is then digested.
