4.4.1.2 Rate of photosynthesis The rate of photosynthesis may be limited by: low temperature shortage of CO2 shortage of light shortage of chlorophyll. Required practical 4: investigate a factor that affects the rate of photosynthesis. State factors that can limit the rate of photosynthesis. Interpret data showing how factors affect the rate of photosynthesis. Required practical: plan a method. 1 Ask students to consider what would happen to a plant if we: put it in the fridge removed CO2 put it in a cupboard took chlorophyll from the leaves. Discuss how the rate of photosynthesis could be measured and consider different methods. Required practical: plan a method. Consider different methods of gathering evidence. Required practical: plan a controlled investigation. Interpret graphs and calculate the rate of photosynthesis. Required practical – see Practical handbook. 4.4.1.2 Required practical: Photosynthesis Investigate the effect of light intensity on the rate of photosynthesis using an aquatic organism such as pondweed. Required practical: carry out an investigation, collect, present and analyse the results. Calculate the rate using numerical information or graphs. 1 Required practical: ask students to identify various factors, select one to control, plan investigation to investigate its effect and explain the procedure and conclusion. Required practical: carry out an investigation, collect, present and analyse the results. Required practical – see Practical handbook. 4.4.1.2 Limiting factors Factors that can the rate of Interpret graphs to decide which factor is limiting the rate. 1 Interpret graphs and explain limiting factors. Plot and interpret data about limiting factors. Mini-greenhouse: plastic food containers
