It is interposed between these two incompatible extremes, and is ordained to transform the innutritions mineral into the proper and indispensable food of the animal kingdom. 741. Pabasitio plants do indeed require the ready organized juices of other plants, just as the carnivora among animals live on flesh. Still the general fact re- mains, that plants alone feed on inorganic matter, and in turn become themselves the food of the animal kingdom. 742. The process of vegetatton consists of imbibing the crude matters of the earth and air, transforming into sap, assimilating to plant juice (latex), and organizing into its own structure according to its own plan. The vital phenomena on which these transformations de- pend are called absortion, circulation, exhalation, assimilation, secretion, fJl of which processes take place in the individual cell. Therefore, T43. Cell-life is an epitome of the life of the whole plant. The cell is never a spontaneous production; it is the offspring of a pre-existing cell. So with the plant; it is always the offspring of a pre-existing embryo or cell. Nothing but it cell can produce or nourish a cell. 744. Two KINDS of organic matter make up the cell. The first protoplasm or protein {C^D H31 Ou Nj), the material of the primordial utricle (§ 645), etc., containing nitrogen; 2d, cellulose, (Cu Hu On,), the material of the outer wall or crust, etc., containing no nitrogen. The former more nearly resembles animal matter, and is the seat of the vital force and chemical action. 745. What the cel^^ im- ^^^ bides.
