Crops absorb and use light energy for the production of photosynthetic products.
Describe how light energy is used by crop plants during the light-dependent reaction.
An experiment using radioactive carbon was carried out by scientists to investigate the Calvin Cycle.
Multiple leaves of a plant were enclosed within a sealed bag containing radioactive carbon for different lengths of time. The leaves were removed and analysed for radioactive compounds.
The graph below shows the results.
Use the graph to explain the changes in the amount of radioactive substances in the dark.
The diagram below is a representation of the light-independent reactions of photosynthesis.
Identify compounds M and O in the diagram.
Describe how plants can use compound P shown in the diagram; another copy of the diagram is included below:
