In the Mind of Plants (2008)

Rating 4/5
Plants are a vital source of life, providing sustenance and oxygen to the human and animal inhabitants of the world. But is plant life closer to sentient life than expected? This documentary from Jacques Mitsch outlines the ways in which intelligence is defined - by recognizing one's environment and interacting with it; having a memory; being able to communicate and interact socially; and having a brain to coordinate everything.
