E School Today: Photosynthesis
Read about photosynthesis, what light and dark reactions are, the structure of a leaf, the conditions needed for photosynthesis to occur, where and how photosynthesis takes place, and how root structure impacts on photosynthesis.
Khan Academy
Khan Academy: The Calvin Cycle
Learn about the three stages of the Calvin Cycle reactions: carbon fixation, reduction, and regeneration of the starting molecule. See how the products of the light reactions, ATP and NADPH, are used to fix carbon into sugars in this cycle.
