What is the fastest growing plant on Earth?

The fastest-growing plant on Earth is bamboo, specifically certain species of Phyllostachys and Bambusa, which can grow up to 91 centimeters (35 inches) in a single day. Bamboo’s rapid growth is a result of its unique structure, where the plant has a strong, flexible stem and an efficient root system. Bamboo is often used in construction, textiles, and paper production due to its sustainability and fast-growing nature, making it an eco-friendly material for various industries.
