Why Study Plants?

Plants provide food and oxygen for the entire biosphere, literally supporting the existence of life on Earth. They also provide shelter, fiber, fuel and medicinal compounds that profoundly affect mankind. Plants fascinate biologists because they regulate ecosystem processes, form complex relationships with other organisms, and have intriguing patterns of development and diversity.
