Part of the In Search Of series, this documentary examines the validity of plants responding to communication. Narrated by series host Leonard Nimoy, In Search of Other Voices takes a look at the world of plants and whether forms of communication affect their growth and development. In return, the concept of whether plants are able to communicate back to the stimuli by changing color or growing in a different pattern is examined. These plant reactions have been studied and scrutinized by scientists and biologists, who discuss some of their research and findings in this video. ~ Cecilia Cygnar, Rovi
