... the same. (5) An equal amount of starch solution should be used with the same concentration. (6) Distance between the table lamp and the vial should be kept the same as light intensity should be kept constant throughout the two experiments. (7) A sufficient amount of enzyme extract and iodine solution in order to get a more observable and clearer result. (8) There should be an equal amount of enzyme extracts for both set-ups. Results: Fresh bean extract: The curve indicates a stable increase in light intensity penetrating the solution as the time lengthens. Boiled bean extract: The curve indicates a stable light intensity penetrating the solution as the time lengthens. Interpretations: Since our observation is that during the germination of a Vigna cylindrical bean, the dry weight of the plant drops before it starts to increase, our hypothesis is that food stored inside the beans are used up during germination for energy for growth by the cells inside ...
