"Plant life" Quotes from Famous Books
 ... controlled by that part of the brain called the medulla oblongata. The respiratory, or breathing process, is not instituted for the benefit of man alone, for we find it both in the lower order of animals and in plant life. Nature is very economical in the arrangement of her plans, since the carbonic acid, which is useless to man, is indispensable to the existence of plants, and the oxygen, rejected by them, is appropriated to his use. In the lower order of animals, the respiratory act is similar ...
— The People's Common Sense Medical Adviser in Plain English • R. V. Pierce
... close together stand the stalks, making common cause for soil and light, each but one of many, the fibre being better when so grown—as is also the fibre of men. Impenetrable and therefore weedless; for no plant life can flourish there, nor animal nor bird. Scarce a beetle runs bewilderingly through those forbidding colossal solitudes. The field-sparrow will flutter away from pollen-bearing to pollen-receiving top, trying to beguile you from ...
— The Reign of Law - A Tale of the Kentucky Hemp Fields • James Lane Allen
... is unable to change lifeless into living matter, but has developed organs of locomotion, ingestion, and digestion which enable it to prey upon the plant world and upon other animal forms; and in contrast with plant life it lives at a loss of energy. Expressed in biological formula, the habit of the plant is predominantly anabolic, that ...
— Sex and Society • William I. Thomas
... be more so now, in view of the fact that only a comparatively few years have elapsed since I began my work on plants. Still, after having used vaccines on human beings and animals for twenty-one years, and observing that plant life reacts to an antigen in a similar manner, I am at least entitled to the same conclusions. This gives me an opportunity of knowing years in ...

... have been carried out in the forcing of plants by means of artificial light. Some of these were conducted forty years ago, when artificial light was more costly than at the present time. Of course, it is well known that light is essential to plant life and in general it is reasonable to believe that daylight is the most desirable quality of light for plants. In greenhouses the forcing of plants is desirable, owing to the restricted area for cultivation. It has been established that some of the ultra-violet rays which are absorbed or not transmitted ...

... with diatoms in a very short space of time, showing that the floating plant life is many times richer than that of temperate or tropic seas. These diatoms mostly consist of three or four well-known species. Feeding on these diatoms are countless thousands of small shrimps (Euphausia); they can be seen swimming at the edge of every floe ...
— Scott's Last Expedition Volume I • Captain R. F. Scott
... the clinging branches of two gigantic ferns, entered the dim wood. He laid the heavy cross beneath a tree, and strolled idly. It was a forest of fronds. Lofty fern trees waved above wide-leaved palms. Here and there a little marsh with crowding plant life held the riotous groves apart. Down the mountain up which the forest spread tumbled a creek over coloured rocks, then wound its way through avenues, dark in the shadows, sparkling where the sunlight glinted through the tall ...
— The Splendid Idle Forties - Stories of Old California • Gertrude Atherton
... is full of interesting information upon the plant life of the seashore, and the life of marine animals; but it is also a bright and readable story, with all the hints of character and the vicissitudes of human life, in depicting which the author ...
— Four Young Explorers - Sight-Seeing in the Tropics • Oliver Optic
... that; some thoughtful men have been led by the analogy between plant life and animal life to believe that something more or less remotely like the consciousness which we attribute to animals must be attributed also to plants. Upon this belief I shall not dwell, for here we are evidently ...
— An Introduction to Philosophy • George Stuart Fullerton
... the odds, that the air of Sirius Three is breathable, he wondered. One in a hundred? The planet has water and both animal and plant life. Certainly it has sufficient gravity to hold its oxygen. But what other elements—noxious gases might be present. Maybe the odds are closer to ...
— The Quantum Jump • Robert Wicks
... inevitable process breaks down the structure of all organic material, partly converting fiber and pulp into gas, partly liquefying the material and converting the remainder into inorganic matter which is of vast importance as food for plant life. A cycle is thus formed which may be best illustrated in the case of cows which feed on the herbage of a meadow, the manure from the cows furnishing food for the grass which otherwise would soon exhaust the nutriment ...
— Rural Hygiene • Henry N. Ogden
... Knowing this law, you need have no fears that base or unworthy thoughts of the reproductive function can ever enter their minds. The growth, development and ripening of human seed becomes a beautiful and sacred mystery. The tree, the rose and all plant life are equally as mysterious and beautiful in their reproductive life. Does not this alone prove to us, conclusively, that there is a Divinity in the background governing, controlling and influencing our lives? Nature has no secrets, and why should we? None at all. The only care we should ...
— Searchlights on Health: Light on Dark Corners • B.G. Jefferis
... makes bosses of gold. But, notwithstanding all this plant beauty, the general impression in looking across the lake is of stern, unflinching rockiness; the ferns and flowers are scarcely seen, and not one fiftieth of the whole surface is screened with plant life. ...
— The Mountains of California • John Muir
... gray-and-red monotony of towns of the Mediterranean peninsulas. Grass sprouted out between the stones of the walls and the tiles of the roofs. From window-ledges and eaves hung ferns. A blush of moss on the stones added to the green of plant life, and softened the austerity of the gray. Nature was successful in asserting herself against man and sun ...
— Riviera Towns • Herbert Adams Gibbons
... the effects of the environment on the colours and structure of animals, the trend of zoology in recent years has returned towards the physiological side, and the old division which separated the sciences (but which has never so seriously affected students of plant life) is being obliterated. ...
