उत्तर
The leaf of a pitcher plant is modified into a slippery, jug - like structure with a lid. When an insect lands on the rim, it slips down the smooth, waxy inner walls into the liquid at the bottom. Downward-pointing hairs inside the pitcher prevent the insect from climbing back out, trapping it completely.
