This groundbreaking scientific film documents futuristic research on plant sensory systems and the environmental significance of understanding what makes plants grow, through the impact of gravity, electrical signals and hormones on plants.
Plants are vital to humankind's existence.
From providing the oxygen we breathe to the foods we eat, plants are a renewable resource upon which our existence depends. Plants, unlike animals, have not developed specific organs that see, hear, and feel various environmental stimuli. Nor can they move to avoid adverse environmental conditions. Yet, plants respond to various environmental stimuli and survive significant fluctuations in environmental conditions. How plants perceive and respond to environmental signals is one of the major unanswered questions in biological sciences.
