Can Plants Think?
The mimosa pudica is a leafy plant that responds to touch by closing up its leaves. This reflex is meant to shoo away insects that land on them. In an experiment, scientists dropped the plant 15cm and watch it close up when it hit the ground. However, the plant stopped closing after being dropped, as it seemed to learn that falling was not a real danger.
