Learn about living organisms in this free online biology course that explores evolution, anatomy, botany and more.

Biology studies life and the vital processes that allow every organism to survive. This course explains how life emerges in all living things from micro to macroorganisms. We lay out their structures, behaviours and relationships to their environment. The course establishes the importance of biology and examines the field’s many branches. We then discuss the types of living organisms and the taxonomic system used to classify them. We then outline the functions of cells.

The course explains how organisms interact ecologically with their surroundings and how humans impact ecosystems and natural resources. We study the biosphere before delving into various theories of evolution that explain the patterns and processes that drive biological change. The course lays out the differences between cells, the cell-to-organ system and the specifics of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) and protein. We examine a wide range of bodily functions and illnesses to show you how the immune system works. We also explore botany to explain the intricacies of plant physiology and their transport systems.

Biology covers a variety of topics related to the viability of life and traces the relationship between the environment and the human body. This course also covers the ecosystem, the nutritional value of food, the aetiology of disease and the development of novel drugs. Biology is an excellent major to choose for your undergraduate degree if you plan to continue your education at the graduate level. It offers a solid foundation on which to base your studies as it is research-focused and adaptable to many fields. Sign up for this biology course to study the science of life and explore the natural world to appreciate your place in it.
