"Or at the delicate tint of that background of leaves? See the rich greens!" "Chlorophyll," murmured the Professor. "Science is so hopelessly prosaic. It dissects and labels, and loses sight of the great things in its attention to the little ones. You have a poor opinion of woman's intellect, Professor Grey. I think that I have heard you say so."
He shows this more fully in regard to the most fundamental of all the vital processes in the plant-body—the breaking up of carbonic acid gas by the chlorophyll to obtain the carbon which is the fundamental element in all living organisms. We know the requisite conditions: the supply of raw material, and the sunlight from which the energy is derived.
"Yes, easily, and some of its contents through the cell's transparent walls, as, for instance, the minute grains of chlorophyll, that is, the green of leaves. All the hues of foliage and flowers are caused by what the cells contain, and these, to a certain extent, can be seen and analyzed.
The chlorophyll in the leaf-cells is now at its prime and the leaves very closely approach a pure green, especially those of the sycamore, which is the nearest to a pure green of any tree in the forest. Standing in the wood road which runs along the top of a timbered crest we look across a broad, wooded valley where the leaves seem to exhale a soft, yellowish green in the bright sunlight.
Another solution envisaged shutting off all light from the grass by means of innumerable radiobeams to interrupt the sun's rays in the hope that with an inability to manufacture chlorophyll an atrophy would set in.
Its greenness is due to its chlorophyll, and it undoubtedly has the manufacturing power in full degree, decomposing carbonic acid and setting oxygen free, under the influence of sunlight.
We'll talk about it on the way in, and go see General Maith at once." Bluelake was peaceful as they flew in over it, but it was an uneasy peace. They began running into military contragravity twenty miles beyond the open farmlands they were the chlorophyll green of Terran vegetation and the natives at work in the fields were being watched by more military and police vehicles.
Large groups of the simpler animals contain chlorophyll, and decompose carbonic acid under the influence of light, as plants do. Large groups of the simpler plants, as you may observe in the diatoms from any stagnant pool, are no less actively locomotive than the minute creatures classed as animals seen along with them.
The tissues of the green surface of the stem and leaves have the peculiar power, when acted on by light, of generating, at the expense of carbonic acid, water and ammonia, with various ternary and quarternary organic compounds, such as chlorophyll, starch, oil and albumen.
And all in silence and in dim light, legions passing along the little jungle roads, unending lines of trembling banners, a political parade of ultra socialism, a procession of chlorophyll floats illustrating unreasoning unmorality, a fairy replica of "Birnam Forest come to Dunsinane." In their leaf-cutting, Attas have mastered mass, but not form.
