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

This 17-minute video lesson provides more detail on the Calvin Cycle and Photorespiration. [Biology playlist: Lesson 32 of 71].

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

This 13-minute video lesson covers the Calvin Cycle or the light-independent (dark) reactions of photosythesis. [Biology playlist: Lesson 31 of 71].

The dark reactions of photosynthesis (Calvin Cycle) are presented in this learning experience to show where these processes take place in the plant as well as the specific reactions involved.

This NetLogo model of leaf photosynthesis shows the macroscopic outcome of the reaction.

Although we generally discuss plants when learning about photosynthesis, keep in mind that plants are not the only organisms that can make their own food. Some bacteria and some protists, such as the algae pictured here, also perform photosynthesis. Learn more about light reactions of photosynthesis in this learning module produced by CK-12.

Problem set tests understanding of Photosynthesis by providing multiple choice questions accompanied by related tutorials. Set 2 Focuses on carbohydrate synthesis.

Page describes Photosynthesis in great detail. Provides an extensive amount of links on all different aspects of photosynthesis. Very thourough.
