How do you check if the destarching has been effective?

Answer 1

To check if destarching has been effective, you can perform a simple experiment using a plant, such as a variegated leaf. After destarching the plant by placing it in the dark for 24-48 hours, expose it to light for a few hours, then test the leaf for starch presence using iodine solution. If the leaf turns blue-black in the areas that were previously green, it indicates that photosynthesis has occurred and that the destarching process was effective. Additionally, the absence of a blue-black color in the non-green areas signifies that starch has not been stored before the experiment.
