Question:
I am designing an experiment for my biology assignment and i was thinking of observing the amount of starch formed from different light sources, eg green red blue... What is the best way to measure the amount of starch in a plant and obtain a number? eg 5 drops of a solution etc I read that by adding vitamin c to starch and iodine solution the dark blue colour could become clear.
