Biology is important because it helps us understand how living things work, how they function, survive and interact on multiple levels. With the advancement of technology, this field of study has broadened and now encompasses the study in the ways to better healthcare for treatment of diseases. It helps us understand how a change in the environment can impact the whole ecosystem. It also helps in finding ways to increase the production of food. It is a versatile field of study and is thus one of the most important sciences that one might consider when choosing a study path.

The main topics included in the study program include survival of living organisms, biological processes, cell theory and genetics. Biology as a subject contributes towards understanding and finding solutions for much health and well being problems that we face in the world. Specifically talking about the medical field, biology helps us in understanding what causes a disease and finds a solution for it in ways of treatment.
