Sequence the steps to check the presence of starch in the colour and green leaves
Answer variants:
Iodine, in the presence of starch, turns into a blue-black colour.
But if the leaf does not turn blue-black on iodine's addition, then it proves it does not do the photosynthesis.
Performing an iodine test will prove that leaves other than green in colour also have stored carbohydrate in them.
Collect one or two plants, one of the leaf should be green in colour and other wth different colour leaves
Remember that the plants undergoing photosynthesis have stored carbohydrates in them.
