Biology A - Sage Online

This course begins with atoms, molecules, and ions. You'll learn the basic properties of atoms and how they form the main types of molecules such as fats, proteins, and DNA. Once you're familiar with the essentials, you'll zoom out a bit to see how these molecules form cells. Using logical thinking to identify relationships and draw conclusions, the course expands out from the building blocks of biochemistry to individual cells and cell membranes to understand cell division, reproduction, cell energy and metabolism, and photosynthesis.
