Plants cover most of the world’s land surface, there are an estimated 400,000 species. Through a process called photosynthesis, plants use sunlight, carbon dioxide and water to produce their own food, as well as releasing oxygen into the air which we need to breathe. Because of this they are vitally important to life on earth. They are also used for food, medicines and even homes for many animals.
Scientists in this zone might be working out how to improve plants being grown for food, how they can be affected by diseases and infections or adapt to different climates. They could be looking at genetically modifying plants, finding new medicines based on plant extracts, or how best to manage important resources like forests.
