Explanation:
hey mate...
if we have extra food at home then we store it in refrigerator.... like that if plant have extra glucose (their food) then they store it in the form of starch.
Hence we keep potted plant in darkness for a day so that plant will use up all its stored starch.. so they will not have any food at last and then we do the experiment .......
