Plants can hear the difference

They respond differently to vibrations caused by 
chewing insects than to wind

University of Missouri-Columbia – Researchers at the University of Missouri-Columbia have found plants can not only tell the difference between the sound waves caused by insects chewing and wind but they respond with more defences. ‘We found that feeding vibrations signal changes in the plant cells’ metabolism, creating more defensive chemicals that can repel attacks
