Trees and shrubs are a type of FLORA, which is a term used to describe all the plant life in a particular area. Trees and shrubs are woody plants that have a permanent stem or trunk and branches that grow from it. They are usually larger than other types of plants, such as herbs and grasses, and can provide food, shelter, and shade. Trees and shrubs are an important part of the natural environment, providing habitats for wildlife and helping to maintain soil fertility.
