by covering some part of leaf with Balck paper such that reaming part of the leaf is left uncovered and then keep the plant for 2to 3 days in sunlight after that take that leaf and test the uncovered part of leaf with idoine then u find the turning of leaf into blue black colour this indicates the presence of starch while the covered portion of leaf doesn't give such result
