In Biology we study living organisms and the processes of life allowing us to understand how plants, animals and microorganisms live and interact with each other and their environment. Biology examines the structure and functions of cells as well as how organisms grow, reproduce and evolve over time. In Biology we learn about genetics and how traits are inherited. The subject explains how systems in the body work both individually and collectively to keep us alive. Biology also studies ecosystems and play an important role in environmental conservation and agriculture. Through biology we gain knowledge about diseases and are able to develop lifesaving medicines.
