INTRODUCTION
Plants produce sugar during photosynthesis.
Carbon dioxide + water + energy = Glucose + Oxygen
CO2 from air H2O energy in sunlight C6H1206 used in plant cells Released to air
Plants convert the sugar into insoluble starch to store it.
The Aim of this experiment therefore, was to test a leaf for starch, to see if the leaf has been carrying out photosynthesis.
The test which would be used would be the iodine test for starch(also known as the "biuret test"). The iodine test for starch will turn the solution blue-black on any area or patches on the leaf where there is starch is present.
