No animal swallows silica, lime, ammonia, or any of the phosphates as food. On the other hand, plants manu- ha^!ffl|uTe^fh^^st^hfe';teXpoi;!'a^oS; facture or produce from in- ^aofo^.l^U'^wUhdraCln^^r^iy': organic matter starch,* sugar mass. and nitrogenous siibstances which constitute the food of animals. During assimilation, plants absorb carbonic acid, and in sunlight exhale oxygen ; during growth and work they, like animals, consume oxygen and exhale carbonic acid. Animals move and have special organs of locomotion ; few plants move, though some climb, and minute forms have thread-like processes or vibratile lashes (cilia) resem- bling the flagella of monads, and flowers open and shut, but these motions of the higher plants are purely mechanical, and not performed by special organs controlled by nerves. The mode of reproduction of plants and animals, however, is fundamentally identical, and in this respect the two king- doms unite more closely than in any other. Plants also, like animals, are formed of cells, the latter in the higher forms combined into tissues. - As the lowest plants and animals are scarcely distinguish- able,, it is probable that plants and animals first appeared contemporaneously ; and while plants are generally said to form the basis of animal life, this is only partially true ; a large number of fungi are dependent on decaying animal ma
