Next time yu find yurself tending t yur flwer garden, yu may want t stay quiet.The flwers are listening.
Israeli scientists discvered that the plants hear bees appraching and attempt t lure them in with sweeter nectar (花蜜)．In several experiments, they fund that playing audi recrdings f buzzing bees arund certain flwers will cause the sugar cncentratin in the nectar t rise by abut 20% in less than five minutes.Such a rapid reactin by plants t sund had never previusly been reprted.Just t make a cmparisn, the researchers als tried a higher frequency nise—like that made by a msquit r a bat—and the flwers did nt respnd.
The authrs pinted ut that the behavir is actually in line with the natural rder f things, cnsidering that a plant's ability t sense its envirnment and respnd t it is critical fr its survival.S, it seems that plants have sme srt f cnsciusness.
This is nt the first time that plants have reacted t the sund arund them.In a 2009 study, the researchers fund that wmen's vices help make plants grw faster.In that experiment, tmat plants were fund t grw tw inches taller when they were tended t by a female gardener.
What if we tld yu that a ptat chip bag left n the flr f a break rm culd listen in n ffice gssip？As peple were talking arund the ptat chip bag, they were sending tiny sund vibratins (震动) int the air.Thse vibratins then hit lifeless bjects arund the rm.If yu had a camera that was zmed in n ne f thse bjects extremely clsely, in thery, yu culd actually see the bject mve alng with the vibratins.Yu culd then feed that vide int a cmputer prgram that culd translate the vibratins and yu culd play back the audi f the cnversatin that just tk place.
S the next time yu're at the btanical garden r in a grcery aisle, be careful what yu say.Smene—r smething—might be listening.
