Excerpt from A Text-Book of Physiological Chemistry IT follows from the law of the conservation of force and matter that living beings, plants and animals, can produce neither new matter nor new force. They are only called upon to appropriate and assimilate already existing material and to transform it into new forms of force. Out of a few relatively Simple combinations, especially carbon dioxide and water, together with ammonium compounds or nitrates, and a few mineral substances, which serve as its food, the plant builds up the extremely complicated constituents of. Its organism, proteids, carbohydrates, fats, resins, organic acids, etc. The chemical work which is performed in the plant must therefore, in the majority of cases, consist in syntheses; but besides these, processes of reduction take place to a great extent. The kinetic energy of the sunlight induces the green parts of the plant to split off oxygen from the carbon dioxide and water, and this reduction is generally considered as the starting-point of the following syntheses. In the first place formaldehyde is produced, co2 h, o z ch, o O which then by condensation is transformed into dextrose, and this then serves in the structure of other bodies. The kinetic energy of the sun, which produces this splitting, is not lost; it is only transformed into another form of force - into the potential energy or chemical tension of the free oxygen on the one side, and the combinations less oxygenated, produced by the synthesis, on the other side.
