Answer:

During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:

transformed into cellulose, proteins and oils

turned into starch for storage

Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.
