The episode begins with a view of greenery and plants all around us, and how little humans know about the complex life of plants. In “The Hidden Power of Plants,” NOVA seeks to unravel the intricate processes in which plants grow, live and reproduce, and the unanticipated ways in which plants influence all types of life on Earth.
Through the episode, viewers are taken on a journey that unlocks the hidden world of plants. Scientists are shown working to discover the purposes and functions of plant mechanisms that go undetected by the naked eye.
The episode introduces viewers to research on how plants communicate and interact with the world around them. We explore how plants use chemicals to defend themselves from insects and pathogens, and how they communicate with their surroundings. For decades, scientists have known that plants release chemicals that can act as signals to other plants, warning them of impending danger or attracting beneficial insects for pollination. However, these signals are incredibly complex, and understanding how they work requires a substantial amount of scientific investigation.
The show examines different species of plants on our planet, ranging from the wild and remote forests to the local plant species growing in the urban areas. Through spectacular footage, viewers are transported into the presence of the world’s oldest and biggest trees and the biggest flower in the world. They get to see how plants co-exist and depend on each other for survival.
One of the most intriguing parts of the show is the section about plant intelligence. Scientists discuss the capability of plants to sense their environment, learn, and remember. For instance, some plants can sense the presence of other plant competitors by their root secretions and adjust their growth to avoid them.
The show also takes us through the functions plants play in our daily life, such as medicine, food, clothing, and shelter. From the aloe vera plant and its healing properties to the production of vanilla, the episode showcases a range of ways in which plants have become an integral part of human life.
In the final moments of the episode, the fascinating role plants play in combating a changing climate is highlighted. As animals, including humans, continue to emit greenhouse gases, trees can absorb and store carbon dioxide, acting as a natural climate solution. The show emphasizes that even small changes in the plant world can have a significant impact on the stability of our environment.
Overall, the NOVA episode “The Hidden Power of Plants” offers a unique and captivating look into the often-overlooked world of plants.
