During photosynthesis, plants absorb light and carbon dioxide to produce glucose.
Describe how the internal structure of a leaf is adapted to maximize light absorption for photosynthesis.
Write the balanced chemical equation for photosynthesis.
A simple controlled experiment can be carried out using a variegated leaf to show that chlorophyll is necessary for photosynthesis.
At the start of the experiment, all of the starch should be removed from the leaf. Suggest how this could be done.
Describe the control in this experiment.
Describe how you would test the variegated leaf for starch. Include the safety precautions you would take and the results you would expect to see.
