To quickly assess the difficulty of the text, read a short excerpt:
In referring to the assimilation of carbon dioxide by green plants and the production of organic food thereby, it was necessary to admit that the details of the process are not satisfactorily known. It is evident, however, that the starch, which is the first substance that we readily recog- nize, is not the first substance which is formed. Modern research points more and more to the conclusion that it is the simplest of carbohydrates that is produced,— a sub- stance known as formaldehyde. But w...hat is especially interesting is that it seems not impossible that this primal reaction may not after all be a function of the living pro- toplasm, but a chemical reaction that can be carried on out- side the cell through the agency of chlorophyll. It is in the further elaboration of this first substance formed that the living protoplasm is apparently necessary. At any rate we know that the energy demanded for the process must be afforded by the particular rays of sunlight which the chlorophyll absorbs.
