    Pseudoscientific claims that music helps plants grow have been made for decades, despite evidence that is shaky at best. Yet new research suggests some flora may be capable of sensing sounds, such as the gurgle of water through a pipe or the buzzing of insects.
    In a recent study, Monica Gagliano, an evolutionary biologist at the University of Western Australia, and her colleagues placed pea seedlings in pots shaped like an upside-down Y. One arm of each pot was placed in either a tray of water or a coiled plastic tube through which water flowed; the other arm had dry soil. The roots grew toward the arm of the pipe with the fluid, regardless of whether it was easily accessible or hidden inside the tubing. “They just knew the water was there, even if the only thing to detect was the sound of it flowing inside the pipe,” Gagliano says. Yet when the seedlings were given a choice between the water tube and some moistened soil, their roots favored the latter. She hypothesizes that these plants use sound waves to detect water at a distance but follow moisture gradients to home in on their target when it is closer.
    The research, reported earlier this year in Oecologia, is not the first to suggest flora can detect and interpret sounds. A 2014 study showed the rock cress Arabidopsis can distinguish between caterpillar chewing sounds and wind vibrations – the plant produced more chemical toxins after “hearing” a recording of feeding insects. “We tend to underestimate plants because their responses are usually less visible to us. But leaves turn out to be extremely sensitive vibration detectors,” says lead study author Heidi M. Appel, an environmental scientist now at the University of Toledo.

De acordo com o segundo parágrafo,

Leia o poema “A última nau”, da obra Mensagem, de Fernando Pessoa, para responder à questão.

Levando a bordo El-Rei D. Sebastião,
E erguendo, como um nome, alto o pendão
Do Império,
Foi-se a última nau, ao sol aziago1
Erma2 , e entre choros de ânsia e de pressago3
Mistério.

Não voltou mais. A que ilha indescoberta
Aportou? Voltará da sorte incerta
Que teve?
Deus guarda o corpo e a forma do futuro,
Mas Sua luz projeta-o, sonho escuro
E breve.

Ah, quanto mais ao povo a alma falta,
Mais a minha alma atlântica se exalta
E entorna,
E em mim, num mar que não tem tempo ou spaço,
Vejo entre a cerração teu vulto baço
Que torna.

Não sei a hora, mas sei que há a hora,
Demore-a Deus, chame-lhe a alma embora
Mistério.
Surges ao sol em mim, e a névoa finda:
A mesma, e trazes o pendão ainda
Do Império.
