DESCRIBE THE MODE OF NUTRITION IN PITCHER PLANT.MENTION THE VARIOUS MODIFICATIONS FOUND IN IT FOR TRAPPING THE INSECTS.

In a pitcher plant, the leaf is modified to form a pitcher like structure. The pitcher has a lid which gets closed when a insects sits on it. In this way, the insect gets trapped in the pitcher. The insect is then digested by various enzymatic secretions.
