NUTRITION 
FIG. 64. Bladderwort (Utricularia s/>.). 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.
