Question

Insectivorous plants are green in colour even then they eat instecs . why ?

Answer 1

plants need some minerals which play an essential role in their survival and pitcher plant is one such plant which grows in swamp or bog areas where the soil is deficient in nitrogen mineral.

In order to fulfill the deficiency of nitrogen, they trap the insects ( these have proteins and proteins are the polypeptide chains which contain amino acids, amino acid in turn has nitrogen as one of its elements ) and utilize their proteins. For this reason it is called insectivorous plant also. It traps prey in rolled leaf that contains a pool of digestive enzymes or bacteria that help in the digestion of the trapped insects.
