An article in Nature Education Knowledge that describes the effect of elevated levels of carbon dioxide in the atmosphere on photosynthesis. This article describes how elevated levels of carbon dioxide causes an increased rate of photosynthesis, which is more pronounced in C3 plants.
Students will learn about the different photosynthetic pathways (C3, C4 and CAM) and how plants respond to changing CO2 levels. They will also learn about biochemical and physiological responses, such as changes in stomatal conductance, water intake, and nitrogen concentrations.
Use this tool to help your students find answers to:
- How do plants generally respond to increases in CO2 levels in the atmosphere? Explain how this varies in C3 and C4 plants.
- Discuss the impacts of elevated CO2 levels on agricultural production and food quality.
- Describe the experimental set-up used in this study to show how plants respond to increased CO2 levels.
