1 . A famous book from the 70s called The Secret Life of Plants says that plants are conscious (有意识的).     1     In one study, plant exposed (裸露) to Mozart were healthier and grew faster than plants exposed to Jimi Hendrix. Some say these studies that claim plants have a taste for music are full of holes. But there is growing research on plant intelligence and plant communication.

Plants don’t have brains so they can’t think in the same way as humans.     2     They can even communicate this information to nearby plants. Researchers in England cut the leaves of cabbages (卷心菜).The threatened cabbages then produced a poisonous gas that protects them from certain insects.     3     Those healthy cabbages nearby seemed to be reacting to a warning from their cabbage neighbors.

    4     Of course, plants don’t have ears, but some scientists think they can feel vibrations. Italian scientist Dr Gagliano recorded clicking noises produced by corn seedlings (幼苗). She then placed these seedlings in water and played them similar sounds. Curiously, the corn seedlings grew towards the loudspeakers.

    5     Whether or not there is an intention to communicate is still up in the air. Whatever the case, plants are stranger and more wonderful than we can imagine.
