This video (13:15) is the eighth in the Crash Course Biology series. It covers the complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we're pretty fond of as well.1) Water 1:162) Carbon Dioxide 1:323) Sunlight/Photons 1:434) Chloroplasts 1:575) Light Reaction/Light-Dependent 2:42a. Photosystem II 3:33b. Cytochrome Complex 5:54c. ATP Synthase 6:16d. Photosystem I 7:066) Dark Reactions/Light-Independent 7:55a. Phase 1 - Carbon Fixation 8:50b. Phase 2 - Reduction 11:31c. Phase 3 - Regeneration 12:02

Reviewer Comments:

Brothers John and Hank Green have created these engaging and accurate “crash course” videos on topics ranging from chemistry to world history, biology, literature, and ecology.  Each video is 10 – 15 minutes long and suitable for all ages, though the content (and humor) may be better suited for middle school through adult learners.  You can learn more about the specific contents of this particular video (from the Biology collection) by clicking the information tab above.  These videos serve multiple purposes well from use in the classroom to facilitating one’s own lifelong learning.
