Journal entry:Information About The bladderwort

Bladderwort is the common name given to the plants of the genus Utricularia.The largest genus of carnivorous plants, it consists of some 215 species which occur in fresh water and wet soil across every continent except Antarctica.Bladderworts are cultivated for their flowers which are often compared with those of snapdragons and orchids.

All bladderworts are carnivorous, and capture small organisms by means of bladder-like traps. Terrestrial species tend to have tiny traps, and feed on minute prey such as protozoa and rotifers swimming in water-saturated soil.The traps are extremely sophisticated.When prey animals brush against trigger hairs connected to the trapdoor, it is released and the bladder sucks in the door and the prey, along with the water surrounding it. Once the bladder is full of water, the door closes again, the whole process taking only ten to fifteen thousandths of a second.

Bladderworts are unusual and highly specialized plants, and the vegetative organs are not clearly separated into roots, leaves and stems as in most other angiosperms. The bladder traps, conversely, are recognized as one of the most sophisticated structures in the plant kingdom.
