Caption

Macrophotograph of leaves of the carnivorous plant Drosera rotundifolia, the sundew, showing the sticky fluid which forms drops at the tips of the tentacles. The tentacles are of two kinds: longer marginal ones & shorter inner ones. Insects, attracted by the droplets, become stuck to the tips of the longer tentacles, which bend over & bring the insect towards the shorter ones, forming a tight grip. Proteolytic enzymes secreted by the tentacles digest the insect, & the products are absorbed by the leaf. Drosera grows in a nitrogen-deficient environment (bogs), which it overcomes through a carnivorous diet.
