bladderwort

(blăd`ərwûrt', –wôrt'), any plant of the genus Utricularia, insectivorous or carnivorous aquatic plants, many native to North America. Small animals are caught and digested in bladderlike organs of the finely divided submerged leaves. Bladderworts and similar related genera are an important element of aquatic and marsh flora on all continents. They are sometimes grown in aquariums as curiosities. Bladderworts are classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

This surprisingly rich history of duplication, paired with the current small size of the bladderwort genome, is further evidence that the plant has been prolific at deleting nonessential DNA, but at the same time maintaining a functional set of genes similar to those of other plant species" says Herrera-Estrella.
The scientists said that it seems that the plant has been busy deleting noncoding "junk" DNA from its genetic material over many generations, which may explain differences between bladderworts and junk-heavy species like corn and tobacco - and humans.

His examples include butterworts that digest and absorb pollen grains that land on their leaves as well as a tropical pitcher plant (Nepenthes ampullaria) that collects leaf debris in its pitchers and various bladderworts (Utricularia), aquatic plants that sometimes catch algae and in some cases seem to maintain algae in their bladders in a mutualism.
