Photosynthesis Video
This video segment from Interactive NOVA: "Earth" explores the history of plant biology. It takes the viewer from the earliest scientific hypotheses that plants ate dirt, to our present-day understanding of photosynthesis, the process by which plants use the sun's energy to convert carbon dioxide and water into carbohydrates, a storable form of chemical energy.
