The carnivorous pitcher plant features a “pitcher” – a modified leaf creating the tube and an overhanging lid – where a sweet, nectar-like liquid collects and attracts insects. Downward-pointing hairs and slippery walls keep the insect trapped in the pitcher, where it eventually slips into the liquid and is dissolved by enzymes so it may be absorbed by the plant. Pitcher plans live in soils poor in nitrogen. They evolved by getting the necessary nitrogen from insects. Photo: Sam Bland
