猪笼草, also known as pitcher plant, is a unique carnivorous plant that captures and digests insects. Its name translates to "pig's basket" in Chinese, referring to its distinctive tubular shape that resembles a pitcher. These plants thrive in nutrient-poor environments, using their specialized leaves to attract and trap prey. The structure of 猪笼草 includes a lid that opens to reveal a liquid-filled cavity. Insects are drawn in by the plant's nectar and slippery walls, making it difficult for them to escape. This adaptation allows 猪笼草 to supplement its nutrient intake, particularly nitrogen, which is scarce in its natural habitat.
