If we want to prove that starch is present in photosynthesis steps are as follow:
1)Take some food material like wheat flour.
2)Put it in a test tube and add some water in it.
3)Add some iodine solution a blue black colour shows the presence of starch.

The potted selected plant should be in the darkness for a night so that it can utilise the starch from the leaves Then the is plant kept in the sunlight for about 3 to 4 hours. Pluck out one leaf boil in alcohol and drop iodine solution on the leaf it turn to blue indicating starch is synthesized during photosynthesis
