INTRODUCTION:-
Most green plants derive their nitrogen from the soil as solute conducted through the root system.However , some of them obtain nitrogen from captured animal prey.Such plants which get their nitrogen from animals are called carnivorous or insectivorous plants .
These plants usually grow in water logged and swampy soils deficient in nitrogenous compounds.
They have poorly developed roots and thus they have to depend on captured insects for their nitrogen requirements.
Infact , these plants do not live solely on the captured animals as they can manufacture their own organic food with the aid of chlorophyll present in their leaves and stems.These plants are , therefore , partly autotrophic and partly hetrotrophic.
Some of the insectivorous plants are
Nepenthes
Drosera
Utricularia
Pinguicula
Dionaea
Sarracenia
Aldrovanda
