The Secret life of Plants
Introduction
—At the beginning of the twentieth century Viennese biologist Raoul Francé 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.
—No plant is without movement; he describes a summer day with thousands of polyplike arms reaching from a peaceful arbor, trembling, quivering in their eagerness for new support for the heavy stalk that grows behind them. When the tendril, which sweeps a full circle in sixty-seven minutes, finds a perch, within twenty seconds it starts to curve around the object, and within the hour has wound itself so firmly it is hard to tear away. The tendril then curls itself like a corkscrew and in so doing raises the vine to itself.
—Plants, says Francé, are capable of intent- they can stretch toward, or seek out, what they want in ways as mysterious as the most fantastic creations of romance.
—Far from existing inertly, the inhabitants of the pasture -or botane- appear to be able to perceive and to react to what is happening in their environment at a level of sophistication far surpassing that of humans.
—Some parasitical plants can recognize the slightest trace of the odor of their victim, and will overcome all obstacles to crawl in its direction.
—Plants seem to know which ants will steal their nectar, closing when these ants are about, opening only when there is enough dew on their stems to keep the ants from climbing. The more sophisticated acacia actually enlists the protective services of certain ants which it rewards with nectar in return for the ants' protection against other insects and herbivorous mammals.
