November 2025 Simon Gilroy Plant Reactions

 

Dr Simon Gilroy, botany professor at UW Madison, presented "Are  my plants listening to me?"  Research has shown that plants have similar senses that we have although theirs aren't controlled by nerves. They can count, like the Venus fly trap that has to be touched twice before reacting, and respond to a chewing insect by alerting other leaves to produce repellents. 

Recording the sound of a chewing insect and playing it back to another untouched plant will cause that plant to react so plants can 'hear'. Plants don't die as soon as they're cut or pulled up so Simon left us with the thought that our salad is 'screaming' at us as we eat!
