Biology is the scientific study of life and living organisms, encompassing everything from the simplest bacteria to the most complex ecosystems. It is a broad field that explores the structure, function, growth, origin, evolution, and distribution of living things. With its wide-reaching impact on health, the environment, and numerous industries, a degree in Biology opens up a world of opportunities for those passionate about understanding the natural world.
What is Biology?
At its core, Biology examines the processes that sustain life, from the cellular level to entire ecosystems. It seeks to answer fundamental questions about how organisms are constructed, how they function, and how they interact with their environment. As a multidisciplinary science, Biology intersects with other scientific fields such as chemistry, physics, and mathematics, as well as areas like computer science and engineering.
Key Areas of Study in Biology
Biology is a diverse field with multiple areas of focus. Here are some of the main branches you can explore:
