On the undersurface of every leaf a million movable lips are engaged in devouring carbon dioxide and expelling oxygen.All together, 25 million square miles of leaf surface are daily engaged in this miracle of photosynthesis, producing oxygen and food for man and beast.When the earth is dry, the roots turn toward moister ground, finding their way into buried pipes, stretching, as in the case of the lowly alfalfa plant, as far as forty feet, developing an energy that can bore through concrete.Tags: Rubric For Ap English Language EssaysFree Argumentative EssaysDo Essay Reference PageWriting An Ap Analysis EssayEarl Spencer Eulogy EssayBritish Essayist Sir RichardProblem Solving At Work ExamplesSample Photography Business PlanBridge Design Research PapersYouth Violence Essay Introduction
Man, said France, merely thinks plants motionless and feelingless because he will not take the time to watch them.
Poets and philosophers such as Johann Wolfgang von Goethe and Rudolf Steiner, who took the trouble to watch plants, discovered that they grow in opposite directions, partly burrowing into the ground as if attracted by gravity, partly shooting up into the air as if pulled by some form of antigravity, or levity.
Our houses are adorned with gardens, our cities with parks, our nations with national preserves.
The first thing a woman does to make a room livable is to place a plant in it or a vase of fresh cut flowers.
On these rootlets of a rye plant are fine root hairs estimated to number some 14 billion with a total length of 6,600 miles, almost the distance from pole to pole.
As the special burrowing cells are worn out by contact with stones, pebbles, and large grains of sand, they are rapidly replaced, but when they reach a source of nourishment they die and are replaced by cells designed to dissolve mineral salts and collect the resulting elements.
The true matrix of human life is the greensward covering mother earth.
Without green plants we would neither breathe nor eat.
As Darwin put it, plants "acquire and display this power only when it is of some advantage to them." At the beginning of the twentieth century a gifted Viennese biologist with the Gallic name of Raoul France put forth the idea, shocking to contemporary natural philosophers, that plants move their bodies as freely, easily, and gracefully as the most skilled animal or human, and that the only reason we don't appreciate the fact is that plants do so at a much slower pace than humans.
INTRODUCTION IX The roots of plants, said France, burrow inquiringly into the earth, the buds and twigs swing in definite circles, the leaves and blossoms bend and shiver with change, the tendrils circle questingly and reach out with ghostly arms to feel their surroundings.
