C1.3.2—Conversion of carbon dioxide to glucose in photosynthesis using hydrogen obtained by splitting water

Experiments

Here are experiments our science specialists have selected to support this IB* topic.

Photosynthesis and Respiration (CO2)

Experiment #31B from Biology with Vernier

In this experiment, you will

  • Use a CO2 Gas Sensor to measure the amount of carbon dioxide consumed or produced by a plant during respiration and photosynthesis.
  • Determine the rate of respiration and photosynthesis of a plant.

Photosynthesis by Chloroplasts

Experiment #12 from Investigating Biology through Inquiry

In the Preliminary Activity, you will use a spectrophotometer to measure color changes in DPIP due to photosynthesis by chloroplasts.

After completing the Preliminary Activity, you will first use reference sources to find out more about photosynthesis by chloroplasts before you choose and investigate a researchable question dealing with photosynthesis. Some topics to consider in your reference search are:

  • photosynthesis
  • chlorophyll
  • chloroplast
  • ATP
  • NADPH
  • electron transport chain
