NUTRITION 



FIG. 64. Bladderwort (Utricularia sp.) . Aquatic insects are held captive 

 in the tiny floating bladders, where they are digested and absorbed. 



FIG. 65. A sundew (Drosera intermedia'), showing the glandular tipped 

 tentacles on the leaves. When an insect alights on a leaf he is held by 

 the sticky secretion; the tentacles then bend over in contact with his body, 

 holding him more firmly, and pouring out a protein-digesting enzyme 

 secreted by their glands.
