Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Describe the Calvin cycle
Define carbon fixation
Explain how photosynthesis works in the energy cycle of all living organisms

College-level online biology course focusing on the process of photosynthesis. Course highlights the physical, chemical, and biological reactions that happen during photosynthesis. Course features include lecture summaries, assignments, and sample student work.
