Carnivorous plants are plants that derive some or most of their nutrients (but not energy ) from trapping and consuming animals or protozoans, typically insects and other arthropods. Carnivorous plants have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. Charles Darwin wrote Insectivorous Plants, the first well-known treatise on carnivorous plants, in 1875.True carnivory is thought to have evolved independently nine times in five different orders of flowering plants, and is represented by more than a dozen genera. This classification includes at least 583 species that attract, trap, and kill prey, absorbing the resulting available nutrients. Additionally, over 300 protocarnivorous plant species in several genera show some but not all of these characteristics.
Trapping mechanisms
Five basic trapping mechanisms are found in carnivorous plants.
Pitfall traps ( pitcher plants ) trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria.
Flypaper traps use a sticky mucilage.
Snap traps utilize rapid leaf movements.
Bladder traps suck in prey with a bladder that generates an internal vacuum.
