What is the fastest-growing plant in the world?

The fastest-growing plant in the world is bamboo, which can grow up to 91 centimetres (35 inches) in a single day under ideal conditions. Bamboo is a type of grass and has an extraordinary ability to grow rapidly, making it an important resource for construction, furniture, and paper production. Its fast growth also helps to prevent soil erosion, and it is highly sustainable due to its ability to regenerate after being harvested.
