           INSECTIVOROUS            PLANTS

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 and rock outcroppings. Charles Darwin wrote Insectivorous Plants, the first well-known treatise on carnivorous plants, in 1875.^[4]

True carnivory is thought to have evolved independently six times in five different orders of flowering plants,^[5][6] and these are now represented by more than a dozen genera. These include about 630 species that attract and trap prey, produce digestive enzymes, and absorb the resulting available nutrients.^[7] Additionally, over 300 protocarnivorous plant species in several genera show some but not all of these characteristics

Trapping mechanisms

The pitchers of Heliamphora chimantensis are an example of pitfall traps.

Five basic trapping mechanisms are found in carnivorous plants

•                     INSECTIVOROUSPLANTS -
• 
  
• . Insects are the most common prey for most carnivorous plants. That is why they are also called as insectivorous plants. There are 9 types and 600 species of insectivorous plants.
• DIET*The diet of insectivorous plants consists of frogs, small mammals and, of course insects.*Most plants absorb nitrogen from soil. However, insectivorous plants receive nitrogen from its prey.
• BEFORE AFTERVENUS FLYTRAP EATING A FLY
• HABITAT*Insectivorous plants mostly live in areas where nutrients are low.*Where they live, water and sunshine are found in enough quantities.*Most of these plants are found in bogs and fens (marshes).
• PITCHER PLANT IN A MARSH
• TYPES OF TRAPS*Insectivorous plants are mainly categorized by the type of trap they have. They are:
• 1-PITFALL TRAPS*The leaves are folded into deep slippery pools.*The pools are filled with digestive juices.*Eg.-Pitcher plant, Nepenthes etc. Nepenthes
• 2-FLYPAPER(OR ADHESIVE) TRAPS*The leaves are covered with stalked glands.*They send out slimy substances to attract insects.*Eg.-Sundews, Butterworts etc. Sundew
• 3-SNAP (OR STEEL) TRAPS*The leaves are hinged so that when the trigger hairs are touched the leaf snaps shut.*Eg.- Venus flytrap, Waterwheel etc. European Waterwheel Waterwheel
• 4-LOBSTER POT*The traps are twisted into cannels lined with hairs and glands.*Eg.- Corkskrew etc. Corkskrew 

passive traps

There are  passive and/or passive traps
