Absorption of Starch from the microscope, using a medium power, soaked beans and the cotyledons from seedlings that have been growing for three or four weeks. Stain the sec- tions with iodine solution, and notice how completely the clusters of starch- grains that filled most of the cells of the unsprouted cotyledons have disappeared from the shriveled cotyledons of the seedlings.
