Light water

Explore the stages of photosynthesis in plants, from light-dependent reactions producing oxygen, ATP, and NADPH to the light-independent Calvin cycle generating glucose. Learn about key experiments by scientists such as Jan van Helmont, Joseph Priestley, Jan Ingenhousz, and Melvin Calvin. Gain insights into how plants convert carbon dioxide and water into sugars.

  1. Light DEPENDENTreactions Light water oxygen ATPNADPH Light INDEPENDENT reactions (Calvin cycle) SUGAR(glucose) Carbondioxide

  2. 6 CO2 + 6 H2O → C6H12O6 + 6 O 2 C6 H12O6 C O2 CO2 H2O

  3. Carefully measured the mass of a growing plant and concluded the increase came from water JAN VAN HELMONT

  4. Experimented with a plant, bell jar, and candle to show that plants make oxygen JOSEPH PRIESTLEY

  5. Showed plants produce oxygen when exposed to light JAN INGENHOUSZ
