Flowering plants that capture and digest animals as a source of nitrogen are labeled "carnivorous." Botanists have described more than 670 species and subspecies of these types of plants. Carnivorous plants thrive in wetlands and bog areas, and need plenty of sunlight. Many types can be grown outside in a bog garden all year.
Characteristics of Carnivorous Plants
To be classified as a carnivorous plant, flowering plants must possess the following characteristics: Plants must have a clear means of capturing it prey; prey must die while in the captivity of the plant; plants must be able to digest the prey into a form that can be absorbed; and plants must be able to assimilate the nutrients from the digested prey.
Types of Carnivorous Plants
Carnivorous plants are grouped by their trapping mechanisms. There are five basic types, categorized as passive or active: pitfall traps, flypaper traps, snap traps, bladder traps and lobster-pot traps.
Carnivorous plants reproduce by producing seeds (sexual reproduction). In some cases, the plant divides, causing asexual reproduction.
More than 95 percent of the U.S. carnivorous plant habitat has been destroyed through the degradation of U.S. wetlands.
Ethnobotany is the study of plants in their relationship to people. Ethnobotanical uses of carnivorous plants include milk curdling and rope making. Some types have also been used in Australia as a food sweetener.
Carnivorous plants can be purchased and grown at home. Some popular types include sundew plants, pitcher plants and Venus flytraps. To be successful, home conditions must simulate the natural habitat of the plant.
