The correct answer is Pitcher Plant.

Concept:

  • Insectivorous plants are the plants that obtain their nutrients by trapping or consuming animals (insects and other arthropods). 
  • Insectivorous plants grow in nitrogen-deficient soils.
  • They obtain nitrogen from different insects, e.g. Drosera, Nepenthes, Dionnea, Utricularia, Pitcher plant, etc.

Explanation:

  • The pitcher plant is an insectivorous plant
  • It has a Pitcher-like structure that is the modified part of the leaf.
  • The apex of the leaf forms a lid that can open and close the mouth of the pitcher.
  • Inside the pitcher, there are hairs that are directed downwards.
  • When an insect lands in the pitcher, the lid closes and the trapped insect gets entangled into the hair.
  • The insect is digested by the digestive juices secreted in the pitcher.
