Caption: Scanning electron micrograph (SEM) of the leaf of a Cape sundew, Drosera capensis, showing a fly (family Psilidae) fallen victim to the insectivorous appetite of the plant. The sundew ensares its victims by means of tentacles capped by globular sticky glands, which simultaneously attract & hold fast the insect. Subsequent struggle stimulates the tentacles, which slowly move in, further entangling the insect. Enzymes are secreted to digest the insect. This mechanism has evolved to supplement the diet of the sundew, growing in mineral deficient environments such as uplands & bogs. Nitrogen in particular is obtained. Mag: X48 (10x8).
