What is Biology?

Biology is the study of life. This includes all living organisms from the simplest to the most complex. The anatomy, development, chemical characteristics, genetics and evolution of a species are all part of the science of biology. The sub-disciplines of biology are many and include biochemistry, cell biology, genomics, physiology, botany, ecology and medicine.

Online Biology Courses and Programs

The study of biology starts with the cell, the basic building block of any living organism. Understanding the structure, function and life cycle of a cell is fundamental to the study of all biological sciences. Build a strong foundational knowledge of cellular biology to help you as you branch out into different areas or specializations. Enroll in the free online course, Cell Biology: Mitochondria, from Harvard University for an introduction to cells and how they work. The self-paced course explores the molecular components of cells with a focus on the mitochondrion, the organelle that powers the cell.

For your next course, step into the world of genetics with Rice University’s free online course, DNA: Biology’s Genetic Code. DNA contains the genetic traits of an organism that get passed on within cells to subsequent generations, continuing the species. Learn the structure of DNA and the methods for packaging DNA into a cell as well as how it can be manipulated and recombined.

EdX offers many more free biology courses from universities and institutions around the world. Explore human anatomy, study genomic data science, learn about ecosystems, evolution and much more.

Learn Basic Biology with Online Beginner Courses

Learn introductory level biology from MIT's Introduction to Biology - The Secret of Life where you will have topics taught in the MIT introductory biology courses and many biology courses across the world. You will learn how to use molecular tools to study biology, describe the building blocks of life and how their interactions dictate structure and function in biology, etc. You will explore the mysteries of biochemistry, genetics, molecular biology, and more biology related topics.

Jobs in Biology and Related Fields

Your interest in biology can take you down many career paths. You can focus on plants, animals or humans in opportunities that can place you in a hospital or clinic, a laboratory, a zoo, a botanical garden or in the middle of the Amazon jungle. Job opportunities and salaries vary widely depending on your specialization. For example, biochemists and biophysicists, who study cell development, growth, heredity and disease, can expect an average salary of $82,180 per year and an 8% job growth rate from 2014 to 2024 according to the U.S. Bureau of Labor Statistics. Biological technicians, who conduct lab experiments, can expect $42,520 per year and a 5% growth rate over the same period. Explore hundreds of other job positions in the field of biology including medical scientist, sociologist, epidemiologist and microbiologist.
