Plant and Environmental Biology is the scientific study of plants. It includes the diversity of plants, their structure, function, ecology and how they interact with other organisms. Plant and Environmental Biology is one of the first scientific disciplines and connects with many other disciplines in the Biological, Physical and Social Sciences. In view of the fact that plants are the primary producers that support all human life, Plant and Environmental Biology has a wider range of applications in many fields. These include; agriculture, biotechnology, environmental science, natural resource management, nature conservation, food and pharmaceutical industries among others. The results of botanical research do not only give insight into plants and the essential processes that affect ecosystems and the natural environment. They also contribute to food, social and economic security. Be it primitive or modern society, plants remain an essential life-support for human existence. This is evident in the role they play in carbon and oxygen cycles, agriculture, building & construction, pharmaceutical, clothing and textile industries.
