Describe the mechanism by which a pitcher plant derives its norishment?

Answer»

Pitcher plant has dual mode of nutrition. It has chlorophyll so it performs photosynthesis using CARBON dioxide, water, and SUNLIGHT and prepare carbohydrates.
But pitcher plant grows in swampy area in bogs where there is a deficiency of NITROGEN. In a pitcher plant, the leaf is modified into a pitcher like structure. The TIP of leaf forms a lid that can open and close the mouth of the pitcher. When an insect gets attracted towards the pitcher and lands on it, the lid close. The pitcher secretes digestive juices which digest the TRAPPED insect.
