According to a new study, plants can “hear” when a bee passes and they subsequently create more sweet nectar to attract them. A recent study by scientists at three Tel Aviv University schools has found that a plant picks up sounds (signaled by the vibration of its petals) and responds (signaled by the excretion of additional nectar). With proof that the flowers responded to all of the tested sounds at various frequencies, the researchers are working to cement the theory that the flowers are in fact the ears of a plant. Also in their hypothesis are explanations for various petal sizes and the evolutionary development of hearing in flowers, rather than in stems or leaves.
