Botany. and thus furnishes a por- tion of its (nitrogenous) food. Venus's Fly-trap, the lobes of whose leaves close and capture insects when the latter touch the slender hairs on the upper side (Fig. 223a), is likewise capa- ble of digesting animal food. The numerous sessile glands provide the digestive secretion, and also absorb into the plant the digested portions of the insects. Glands, whose viscid secretion is capable of digesting nitrogenous material, are also found on the leaves of the Butterwort {Pkiguunda), which grows on wet rocks and damp soils. The curious little bladders (Fig. 224) of the Bladderwort {Utricuhria) capture small water-animals. In the pitchers (Fig. 225) of the Sarraeenia and Nepenthes, insects fall and drown; these animals, by their decay, probably furnish food to be absorbed by the plants. 137. The immediate products of-assimilation undergo further (though but slightly understood) chemical changes to form the various substances found in vegetable tissue. All these changes, subsequent to assimilation, are collectively termed metastasis (Gr. meta, over; idamai, to place). Metastasis is a process of oxidation; 225 Fig. 223a.
