Answer:
In insectivorous
plant, e.g., Nepenthes, the leaf lamina gets modified in the form of pitcherand
anterior part of petiole coils like tendril which keeps the pitcher in a
vertical direction.
Posterior part of
the petiole remains flattened like a leaf. The apex of lamina forms a lid.
Pitcher
contains digestive enzyme which digest the trapped insects.
All these
modifications and adaptation are developed to make up the nitrogen deficiency
inthe plant because these plants are found in deficient
soil, (marshy/swamp soils)
